But on the flip side, urethane isn’t as pretty or UV-friendly as ABS, so you can’t simply develop a product that’s ready to go on the vehicle in its natural form like as you can with ABS. (Think: insulation.) hbspt.cta._relativeUrls=true;hbspt.cta.load(3848240, '9ce69f01-ee0c-4570-9e76-71c4884063bd', {}); © 2018 Mearthane Products Corporate Terms & Conditions / Privacy Policy. In short, “complicated” means “expensive,” which means higher production costs and higher consumer costs. However, that also means it can’t be repeatedly melted down and recast into new parts. ABS is rigid, versatile, but not good for outdoor exposure (poor UV resistance). As stated, ABS plastic and polyurethane have their own advantages in terms of manufacturing. Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. You’re not off-roading on Mars. Thermoplastics are strong but flexible, making them great for high-impact applications, like these Penda drop-in bedliners. But, truthfully, the plastics and polys of the world are what really put the proper finishing touches on a vehicle. Both have advantages and disadvantages depending on what they are used for. 04-05-2009 12:25 AM #2 Plus, ABS plastic is very widely used by OEM for body panels. It also has increasing load-bearing capacity, impact-resistance, and excellent wear properties. This material is very appealing to the eye even in raw form and it’s easier to paint than polyurethane. Furthermore, it is resistant to harsh environmental factors such as heat, oil, and acids. Below-the waterline through-hull fittings are in this group, but when there is any doubt, select an alternative sealant. But let’s get back to it. What ABS and Polycarbonate Have in Common. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available.. Polyurethane polymers are traditionally and most commonly formed by reacting a di- or triisocyanate with a polyol. Acrylonitrile Butadiene Styrene (ABS) is an engineered thermoplastic formed by three synthetic materials, while polyurethanes are typically identified as a thermoset. And when you factor in the issues that the elements pose on these materials (unless properly finished and cared for), they just aren’t the most viable solution. So, what about fiberglass? Helping Solve the Age-Old Question: Lease or Buy. There are a few physical properties that make both ABS and polycarbonate useful for engineering.. What makes them great for helmets is that they are resilient to impact, and can survive a wide range of temperatures. “The last two years, we’ve been working on this material that we introduced in our SEMA booth,” says Longfellow, referring to AirDesign USA’s impressive new product lineup for the JL Wrangler at SEMA 2019. It’s the combination of both—you can inject it and you could basically hit it with a baseball bat.”, “With this new material, we’re going to be able to start injecting things like fenders and hoods, and that’s something we’re really excited about,” says Longfellow. ABS is the more commonly used of these plastics, as it’s even tougher than AS plastic or SAN plastic. Polycarbonate (PC) is also temperature resistant, and somewhat flame retardant/self-extinguishing. Polyurethane is similar to ABS in strength and versatility, but ultimately is created and applied differently. Advantages of Polyurethane: Substituting polyurethane components for rubber or plastic may offer the following advantages, just to name a few. And, like Longfellow points out, a benefit in ABS’s corner is the finish. Sorry, your blog cannot share posts by email. ABS is an acronym for acrylonitrile butadiene styrene. Creep resistance can be defined as a material's ability to resist any kind of distortion when under a load over an extended period of time. This material is a great choice for most product enclosures. Urethane would be like you’re missing a hand and you can inject that hand. Instead, we are here to talk about two very prevalent types of plastics in the automotive industry— Polyurethane and ABS —and how they compare to one another. This is a strong thermoplastic polymer commonly used on the exterior of vehicles in the form of mud flaps, fender flares, trim, and so on. To help us further understand the topic, we turned to Billy Longfellow, VP of Design at AirDesign USA. The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc. What is ABS plastic, anyway? While bonding ABS can be done with a variety of types of plastic adhesives (plastic glues), a few of the most common include cyanoacrylate, 2 component epoxy, structural acrylic, and UV curable adhesives. So, what’s going to happen is it’s going to have a bow in the middle because it’s going to buckle out.”. Examples of plastics consists of polyethylene, PVC, nylon and ABS. Unlike ABS, which is a thermoplastic, polyurethane is a thermosetting plastic. Typically, we find this material used for seat foam, in the windows, flooring, and even in the bumpers. And, let’s not forget, recycling can be a hassle, too—a drawback that can be very costly as the world turns toward greener initiatives. However, they are not resistant to aromatic and chlorinated hydrocarbons. High Performance adhesives, glues, primers, sealants and solvents for joining Polyurethane surface to ABS surface. However, even then, the material isn’t a waste. In the latter part of a decade, we’ve seen electric cars become normalized, smartphones become mega processors, and machinery become (nearly) self-aware. Tensile Strength . However, this is not to say that polyurethane doesn’t have its drawbacks, too. And even in low temperature conditions or over long periods of time, ABS plastic will retain these characteristics. Elongation at Break . (In fact, some exterior parts, such as spoilers, are constructed of it as well.) ABS Plastic parts vs Polyurethane parts: PinnacleChronos: Newbies & FAQs: 3: 01-11-2007 03:51 PM: FRP (fiber reinforced plastic) vs ABS/Urethane pieces: BIGSKYWRX: Interior & Exterior Modification: 7: 10-13-2004 11:16 PM: 2004 STI V-Limited Lip - ABS Plastic in stock now! So, in addition to unpacking their similarities and differences, let’s explore what kind of products they’re used to create and whether one is better than the other. Strictly speaking, thermoset polyurethanes are NOT considered a "plastic". PVC and ABS pipes are resistant to most acids, alkalis and salts. ABS vs. PVC Plastic. Unlike thermoset polyurethane, plastics will tend to remain permanently deformed or even break when stretching, abrasion or impact forces are applied. The holiday season is coming in hot and with delivery times longer than ever, it’s time to finish up that. and fibreglass breaks etc. Generally, polyurethane is a favorite among engineers, not only because it can come in both rigid and flexible forms, but also because it’s a very tough material and can withstand high-stress environments. Arm rests, head rests, cushioned instrument panels and other parts of your car’s interior are all made with polyurethane foams. ______________________________________Other Related Topics____________________________________________. However, because you only get one-sided molds, there are hurdles to overcome for mounting solutions that are otherwise easily solved with urethane. But, while it has its advantages, fiberglass is difficult to manufacture. Like polyurethane, ABS plastic is more expensive and heavier than fiberglass. The advantage of ABS plastic is that you can have an extrusion. So, it’s basically like putting a glove on your hand that’s vacuum-forming. 2020 Gift-Giving Guide: Ideas for the Motorhead on Your Shopping List, Fab Fours Keeps It Fresh With Original NEW Designs, Auto Industry News: Big Recalls, New Vehicle News and More Bureaucratic Buzz, Competition Corner: Get In the Holiday Spirit with December 2020 Auto Events, Activate More Grip With Whiteline Suspension Parts, we’ve seen electric cars become normalized, Trend-Spotting: New 2020 Trucks Meet, Exceed, and Set New Expectations, Helpful Tips for Selecting the Right Toolbox for Your Truck, Auto Industry News: Baja 1000 Results, V-8 Wrangler Rubicon, Polaris Shake-Up and Self-Driving Racecars, Auto Industry News: Hipster Smart Car, Self-Balancing Motorcycle and More, 2016 Mazda CX-9: Meticulously Crafted for Drivers, Mustang vs Camaro: Age-Old Rivalry Alive and Well, Off-Road Checklist: Be Smart, Go Prepared, Behind the Wheel with NHRA Driver Peter MacRitchie, Tackling Rust Prevention and Removal Part I, CARR LD Steps Take Worker Safety Seriously… And So Should You. “Urethane in its natural state is white, so most people put a carbon black in it to hide all the imperfections,” explains Longfellow. Plus, while fiberglass has good load-bearing strength, it doesn’t hold up exceptionally well to impact situations, meaning it can crack under shock. Remember, Supply and Demand, BMW is building more ... Hooah! For optimum performance and maximum lifetime, engineering plastics, which are subjected to long-term loading, should have a high creep resistance (ie. But, overall, its characteristics lend it more toward performance than styling. Think of polyurethanes more like a combination of rigid plastic and strong rubber. That is, unless you heat it to its melting point or freeze it to the point of fracture. “Now, instead of making a hood scoop, we’re going to be able to inject a hood—and it’s going to be lightweight and strong, too.”. Material Properties. It’s also been something that’s subjected to verbal abuse on account of both misunderstanding and common myth. Use Them to Your Advantage! ABS plastic is also easily recyclable , which is another point in it’s favour. So, not only is the material more costly than polymers and plastics, but so is the necessary machinery. 2 Stress-Strain Behavior of Thermoplastic Polyurethane H.J. Two of the most widely used thermoplastics are Acrylonitrile Butadiene Styrene, or ABS, and Polyvinyl Chloride, or PVC. A = No Attack, possibly slight absorption. This new material AirDesign has been working on is specifically designed to marry the best of both worlds—something that could reshape the entire industry! Impact strength varies by grade. To start, let’s look at the difference between casting and molding. ABS Plastic vs Polyurethane front lips; For full access to all sections of JDMST you must register; Page 1 of 2 1 2 Last. ABS is by far the strongest plastic used for making figurines. Because of this, some local regulations require ABS pipes to contain pigments to protect it from UV radiation or to be painted with latex paint. So, have we begun to harness this information in a way that we auto enthusiasts can really begin to have fun with? It can be applied over both flexible and rigid substrates such as flexible PVC and plastic coatings. Although ABS plastic may not offer the same level of resiliency, it has high rigidity and impact resistance. “Plus, urethane is not UV-stable, so it has to have a coating on it. Post was not sent - check your email addresses! But, suffice it to say, that it’s way stronger than most people think. The most important features impacted by material type are flexibility and temperature resistance. But in a real-world consumer scenario—say, when purchasing fender flares—how much does this really matter? Furthermore, the fact that polyurethane has strong sound absorption means it’s often used for suspension bushings, which is something many drivers are seriously thankful for. Unlike thermoset polyurethane, plastics will tend to remain permanently deformed or even break when stretching, abrasion or impact forces are applied. Qi1,2, M.C. This isn’t to say that polyurethane can’t be pretty, too. Thermoset polyurethanes have many advantages over plastics for a variety of applications, including: To learn more about thermoset polyurethane and how it can improve your product's performance compared to other known materials - Make sure to download our white paper, here, or click the banner below. Legend. Think of polyurethanes more like a combination of rigid plastic and strong rubber. You could have an A and B side of a mold and you could have a back side of it for attachment.”. Chemical Resistance for Plastics - Find plastic materials and their resistance to different chemicals. This construction makes them very durable but a little trickier to recycle. 16% . So, on paper it might seem like polyurethane is the chief winner, right? Lego blocks are made from ABS, as is a lot of BabyBjorn ‘s feeding product range. Let’s not ignore the 800-pound gorilla named “Technology” in the room. Well, sure, but we should take a look at it from the manufacturer’s perspective. Both ABS and polycarbonate are plastic, like much of the rest of your helmet.. Material Comparison - ABS/Polyurethane and PTFE Filled Write By: sukoptfe Published In: PTFE Polymer Created Date: 2017-03-17 Hits: 8667 PTFE 's significant chemical, temperature, moisture, and electrical resistances make it an ideal material whenever products, tools, and components need to be durable and reliable in even the most strenuous applications. Plastics are vital to just about all aspects of society, from consumer products and transportation to heavy manufacturing and infrastructure. Boyce1 1Department of Mechanical Engineering, Massachusetts Institute of Technology Cambridge, MA 02139 2Department of Mechanical Engineering, University of Colorado Boulder, CO 80309 Submitted in December 2003 Revised in July 2004 Those ABS parts on your Jeep can easily withstand the typical impact, heat, and chemical abuse found on the trail and look better doing it—all at a lower price to boot. The plastics family generally include materials with a wide range of chemical compositions, including variations of carbon and hydrogen molecules. But because of its versatility and toughness, polyurethane is often found in areas where abuse is the name of the game. Much like polyurethane, ABS plastic also has superior fit and finish that is found to be more expensive than fiberglass. Now, these materials can vary in terms of the manufacturing process, too. But, generally speaking, they are more affordable and easier to work with than metal on a grand scale. and polyurethane is the soft one. “Both are going to grow and shrink with the weather. Thermoset … We live in the future! Polyurethane has exceptional abrasion and tear-resistance, typically better than rubber. Durability. See the chart below for ABS yield strength, Young’s modulus (ABS elasticity), tensile yield strength of ABS plastic, mechanical properties of ABS plastic, and other properties. Not only that, they don’t rust or corrode like metal, and they’re lighter and more forgiving on other materials. Typically, thermoset polyurethanes are either cast molded or Reaction Injection Molded (RIM), while plastics are often injection molded. ABS plastics are two-phase systems. The polyurethane is more flexible and thus won't shatter when rubbed against a curb or whacked. The answer is yes. Polyurethane is similar to ABS in strength and versatility, but ultimately is created and applied differently. = Acrylonitrile Butadiene Styrene This is a common thermoplastic which is rather easy to bond. Thermal Properties of Plastic Materials Material Formula Coefficient of thermal expansion x10-6 K-1 Heat-deflection temperature - 0.45MPa C Heat-deflection temperature - 1.8MPa C ... ABS 80 98 89 - - 0.17 @23C 70-100 Polyamide - Nylon 6 PA 6 95 200 80 -40 1700 0.24-0.28 @23C 80-160 Polyamide - … Have a question on the chemical resistance of plastics? Fiberglass doesn’t hold up very well to high-impact stress. Long story short, there are some areas where plastics and polyurethanes are the only solution. ABS-Like is a general purpose polyurethane plastic that simulates ABS thermoplastic. ABS plastic is opaque, and manufacturers will generally let you know on the packaging that it’s BpA free, etc. That means, it forms really strong bonds when heated up—making it great for heat-resistant products. Sheet metal can often be difficult to work with for manufacturers, as it needs to be stamped into shape. Polyurethane is complicated to produce. “They both have their pitfalls,” says Longfellow. ABS is vacuum-formed and comes with an existing UV-resistance. The binding matrix layer of SAN makes the two phases of the polymer compatible. Instead, the long flexible polymer molecules that comprise thermoset polyurethanes make this material a true elastomer. When comparing, ABS VS Polycarbonate, for patterns and colors, polycarbonate always wins. Hardness . 1/4 " abs plastic can be bent using a heat gun to soften it up and then shape it manually.. And what is the difference? It’s a little less flexible than polyurethane, but it’s found to be easier to paint. The advantage is that it combines the strength and rigid properties, as well as the rubbery toughness (ABS can bend without snapping). We’re not here to talk about how plastics stack up against other materials commonly used on automobiles. That thing is going to grow maybe a quarter of an inch by the end of the summer. Which ABS adhesive is best? What is polyurethane? Urethane doesn’t have the coating, so over time it’ll turn chalky white,” he adds. Both types of piping can be used above or below the ground, but ABS is more likely to deform when exposed to the sun. Let’s say you have a side skirt on a F-150. Styrene-acrylonitrile (SAN) forms the continuous matrix phase. Also see . ABS plastic is less flexible than polyurethane, but it's a very easy surface to apply paint on. low plastic deformation under load). Keep an eye on AirDesign to see what else they do with this technology and be on the look out at upcoming trade shows to see how other aftermarket suppliers are innovating in the sphere. just very confusing. Polyurethane plastic is normally used as a foam (rigid or flexible), instead of made into solid objects. Typically, thermoset polyurethanes are either cast molded or Reaction Injection Molded (RIM), while plastics are often injection molded. Plastic marine fittings are typically ABS or PVC, and polysulfide will attack both. Nylon and polyurethane are two popular choices for tubing materials. Polyurethane vs. Nylon. And, yes, it can stand up better to high-heat environments. The problem with ABS is that you don’t have a backside to it. It's a minor annoyance in my BMW 335d to have to p...

That doesn’t mean polyurethane can’t be recycled, just that the process is a little more complex. Extruded plastic can have a DOC coating, so you don’t have to paint it. In fact, thermoplastic materials can go through these heating and cooling cycles several times without changing their fundamental makeup. What is ABS? Some tubing and pipes are polyurethane, however. With decades of experience under his belt, he possesses a keen understanding of these materials. In your car, you can find polyurethane used for interior parts such as the flooring and even bushings in the suspension. Acrylonitrile Butadiene Styrene (ABS) is a blend of three different plastic materials – Acrylonitrile, Butadiene, and Styrene. For reference, “thermoplastic” implies that the material gets soft when heated and hard when cooled. for a variety of applications, including: Superior durability and resiliency at harder, Physical properties can be engineered to meet demanding specifications. It is important to note that density varies with temperature. “We did flares with it, a new grille with it, and we did our new bumper. Negligible effect on mechanical properties. However, as mentioned, when seeking parts that are going to see major, prolonged abuse—you want a material that can stand up to the challenge. This construction makes them very durable but a little trickier to recycle. I read that ABS plastic is the hard solid plastic and that the bumpers were made from it but theyre sorta flexible. And, in that case, polyurethane will gain your vote of confidence. That’s why you’ll see all of these fender flares in black or satin black—because it already has the coating. ABS plastic remains hard, rigid and tough even at low temperatures. The second phase is composed of dispersed polybutadiene particles, which has a layer of SAN grafted onto their surface. Unlike ABS plastics, thermoset polyurethanes do not melt when heated, instead, they are formed through a two-part liquid system. Plastic has long been a go-to material in the automotive world. Your partner in precision urethane-based technology from prototype to production. Additionally, it has to be worked by hand, meaning that the fit and finish can vary and natural defects will show. This crack formed when the driver’s bumper came into contact with a higher-than-normal railway crossing. Issues like corrosion, weight, and cost come into play. 1,487 Posts . Innovation has given us the means to overcome incredible leaps and bounds! Well, in the past, fiberglass was used by many automakers to produce lightweight components like hoods, and is still pretty widely available today. Ask a Plastic … PVC is usually made softer and more flexible by the addition of plasticizers. Longfellow sheds a little light on why this is: “The urethane is going to grow longer. Density measures the mass per unit volume.It is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm 3. Some swelling and a small reduction in mechanical likely. Gruppe-S: Exterior/Styling: 20: 03-27-2004 12:08 AM Urethane casting vs. plastic injection molding, for instance — two processes that are, on the surface, relatively similar — can yield vastly different results depending on your requirements and expectations. As a result, thermoplastics are mechanically recyclable.”. Polyurethane (rigid) is stronger than ABS, but harder to work with (cut, mold, etc). Unlike ABS, which is a thermoplastic, polyurethane is a thermosetting plastic. However, it also offers fit and finish that's superior to fiberglass. “These characteristics, which lend the material its name, are reversible, so the material can be reheated, reshaped, and frozen repeatedly. 72.6 MPa . Thanks for all your answers! “Polyurethanes exist in a variety of forms, including flexible foams, rigid foams, chemical-resistant coatings, specialty adhesives and sealants, and elastomers,” explains the American Chemistry Council. While metal is an ideal material in terms of durability, it’s not always the most practical solution for certain accessories. If you know that the plastic fitting is made of epoxy, nylon, or Delrin, you can safely bed it with polysulfide. It is available in fire-retardant, heat-resistant and platable grades. So, yes, polyurethane is stronger than ABS plastic. Sure, we all get giddy thinking about the iron and aluminum in our cars. B = Slight attack by absorption. “Thermoplastics are defined as polymers that can be melted and recast almost indefinitely,” explains PlasticsEurope, a leading trade association that represents plastics manufacturers. It’s a one-sided mold. They Are Good Engineering Materials. So while PVC is soft and rubbery in resilience, ABS is tough and rigid. They also look great in raw form.
