Well, sure, but we should take a look at it from the manufacturer’s perspective. “Thermoplastics are defined as polymers that can be melted and recast almost indefinitely,” explains PlasticsEurope, a leading trade association that represents plastics manufacturers. The holiday season is coming in hot and with delivery times longer than ever, it’s time to finish up that. 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. Let’s say you have a side skirt on a F-150. Durability. Styrene-acrylonitrile (SAN) forms the continuous matrix phase. As a result, thermoplastics are mechanically recyclable.”. 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. And even in low temperature conditions or over long periods of time, ABS plastic will retain these characteristics. Polyurethane (rigid) is stronger than ABS, but harder to work with (cut, mold, etc). Nylon and polyurethane are two popular choices for tubing materials. Acrylonitrile Butadiene Styrene (ABS) is an engineered thermoplastic formed by three synthetic materials, while polyurethanes are typically identified as a thermoset. 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. ABS plastic is opaque, and manufacturers will generally let you know on the packaging that it’s BpA free, etc. But, suffice it to say, that it’s way stronger than most people think. It is important to note that density varies with temperature. “Urethane in its natural state is white, so most people put a carbon black in it to hide all the imperfections,” explains Longfellow. The answer is yes. This material is a great choice for most product enclosures. Tensile Strength . Remember, Supply and Demand, BMW is building more ... Hooah! Some tubing and pipes are polyurethane, however. Plastic marine fittings are typically ABS or PVC, and polysulfide will attack both. 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. That thing is going to grow maybe a quarter of an inch by the end of the summer. 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. 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. This crack formed when the driver’s bumper came into contact with a higher-than-normal railway crossing. 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. Thermoplastics are strong but flexible, making them great for high-impact applications, like these Penda drop-in bedliners. “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. It is available in fire-retardant, heat-resistant and platable grades. You’re not off-roading on Mars. They also look great in raw form. This material is very appealing to the eye even in raw form and it’s easier to paint than polyurethane. Issues like corrosion, weight, and cost come into play. ABS is an acronym for acrylonitrile butadiene styrene. They Are Good Engineering Materials. Two of the most widely used thermoplastics are Acrylonitrile Butadiene Styrene, or ABS, and Polyvinyl Chloride, or PVC. It's a minor annoyance in my BMW 335d to have to p...

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! Long story short, there are some areas where plastics and polyurethanes are the only solution. 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. ABS plastic is less flexible than polyurethane, but it's a very easy surface to apply paint on. This construction makes them very durable but a little trickier to recycle. However, because you only get one-sided molds, there are hurdles to overcome for mounting solutions that are otherwise easily solved with urethane. and fibreglass breaks etc. Polyurethane is similar to ABS in strength and versatility, but ultimately is created and applied differently. What ABS and Polycarbonate Have in Common. But in a real-world consumer scenario—say, when purchasing fender flares—how much does this really matter? 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! Polyurethane plastic is normally used as a foam (rigid or flexible), instead of made into solid objects. Both have advantages and disadvantages depending on what they are used for. “They both have their pitfalls,” says Longfellow. So, have we begun to harness this information in a way that we auto enthusiasts can really begin to have fun with? It’s a one-sided mold. “These characteristics, which lend the material its name, are reversible, so the material can be reheated, reshaped, and frozen repeatedly. Negligible effect on mechanical properties. Sheet metal can often be difficult to work with for manufacturers, as it needs to be stamped into shape. You could have an A and B side of a mold and you could have a back side of it for attachment.”. So, what about fiberglass? However, it also offers fit and finish that's superior to fiberglass. That doesn’t mean polyurethane can’t be recycled, just that the process is a little more complex. “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. The binding matrix layer of SAN makes the two phases of the polymer compatible. Ask a Plastic … This construction makes them very durable but a little trickier to recycle. But let’s get back to it. Elongation at Break . Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. 72.6 MPa . Let’s not ignore the 800-pound gorilla named “Technology” in the room. Acrylonitrile Butadiene Styrene (ABS) is a blend of three different plastic materials – Acrylonitrile, Butadiene, and Styrene. Legend. So, what’s going to happen is it’s going to have a bow in the middle because it’s going to buckle out.”. Some swelling and a small reduction in mechanical likely. And, like Longfellow points out, a benefit in ABS’s corner is the finish. What is ABS? ABS plastic remains hard, rigid and tough even at low temperatures. Much like polyurethane, ABS plastic also has superior fit and finish that is found to be more expensive than fiberglass. It can be applied over both flexible and rigid substrates such as flexible PVC and plastic coatings. Both ABS and polycarbonate are plastic, like much of the rest of your helmet.. So, it’s basically like putting a glove on your hand that’s vacuum-forming.

Fiberglass doesn’t hold up very well to high-impact stress. And, yes, it can stand up better to high-heat environments. ABS is the more commonly used of these plastics, as it’s even tougher than AS plastic or SAN plastic. 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. Plus, while fiberglass has good load-bearing strength, it doesn’t hold up exceptionally well to impact situations, meaning it can crack under shock. ABS Plastic vs Polyurethane front lips; For full access to all sections of JDMST you must register; Page 1 of 2 1 2 Last. Like polyurethane, ABS plastic is more expensive and heavier than fiberglass. While metal is an ideal material in terms of durability, it’s not always the most practical solution for certain accessories. Sorry, your blog cannot share posts by email. The most important features impacted by material type are flexibility and temperature resistance. hbspt.cta._relativeUrls=true;hbspt.cta.load(3848240, '9ce69f01-ee0c-4570-9e76-71c4884063bd', {}); © 2018 Mearthane Products Corporate Terms & Conditions / Privacy Policy. ABS is by far the strongest plastic used for making figurines. Although ABS plastic may not offer the same level of resiliency, it has high rigidity and impact resistance. It’s a little less flexible than polyurethane, but it’s found to be easier to paint. In fact, thermoplastic materials can go through these heating and cooling cycles several times without changing their fundamental makeup. So, not only is the material more costly than polymers and plastics, but so is the necessary machinery. 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. Additionally, it has to be worked by hand, meaning that the fit and finish can vary and natural defects will show. The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc. Polyurethane has exceptional abrasion and tear-resistance, typically better than rubber. 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 This isn’t to say that polyurethane can’t be pretty, too. Typically, thermoset polyurethanes are either cast molded or Reaction Injection Molded (RIM), while plastics are often injection molded. Urethane doesn’t have the coating, so over time it’ll turn chalky white,” he adds. Use Them to Your Advantage! ______________________________________Other Related Topics____________________________________________. Polycarbonate (PC) is also temperature resistant, and somewhat flame retardant/self-extinguishing. High Performance adhesives, glues, primers, sealants and solvents for joining Polyurethane surface to ABS surface. So, yes, polyurethane is stronger than ABS plastic. And, in that case, polyurethane will gain your vote of confidence. Think of polyurethanes more like a combination of rigid plastic and strong rubber. ABS plastic is also easily recyclable , which is another point in it’s favour. 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. “Plus, urethane is not UV-stable, so it has to have a coating on it. Typically, we find this material used for seat foam, in the windows, flooring, and even in the bumpers. 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. The plastics family generally include materials with a wide range of chemical compositions, including variations of carbon and hydrogen molecules. If you know that the plastic fitting is made of epoxy, nylon, or Delrin, you can safely bed it with polysulfide. But, while it has its advantages, fiberglass is difficult to manufacture. Your partner in precision urethane-based technology from prototype to production. What is ABS plastic, anyway? Post was not sent - check your email addresses! Qi1,2, M.C. Innovation has given us the means to overcome incredible leaps and bounds! 2 Stress-Strain Behavior of Thermoplastic Polyurethane H.J. 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. ABS vs. PVC Plastic. That’s why you’ll see all of these fender flares in black or satin black—because it already has the coating. It’s also been something that’s subjected to verbal abuse on account of both misunderstanding and common myth. 1,487 Posts . “Both are going to grow and shrink with the weather. Chemical Resistance for Plastics - Find plastic materials and their resistance to different chemicals. for a variety of applications, including: Superior durability and resiliency at harder, Physical properties can be engineered to meet demanding specifications. Now, these materials can vary in terms of the manufacturing process, too. Arm rests, head rests, cushioned instrument panels and other parts of your car’s interior are all made with polyurethane foams. Unlike ABS plastics, thermoset polyurethanes do not melt when heated, instead, they are formed through a two-part liquid system. 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. But, generally speaking, they are more affordable and easier to work with than metal on a grand scale. It also has increasing load-bearing capacity, impact-resistance, and excellent wear properties. Furthermore, it is resistant to harsh environmental factors such as heat, oil, and acids. Unlike thermoset polyurethane, plastics will tend to remain permanently deformed or even break when stretching, abrasion or impact forces are applied. To help us further understand the topic, we turned to Billy Longfellow, VP of Design at AirDesign USA. That means, it forms really strong bonds when heated up—making it great for heat-resistant products. In the latter part of a decade, we’ve seen electric cars become normalized, smartphones become mega processors, and machinery become (nearly) self-aware. Polyurethane vs. Nylon. The problem with ABS is that you don’t have a backside to it. 04-05-2009 12:25 AM #2 Polyurethane is similar to ABS in strength and versatility, but ultimately is created and applied differently. Strictly speaking, thermoset polyurethanes are NOT considered a "plastic". So while PVC is soft and rubbery in resilience, ABS is tough and rigid. As stated, ABS plastic and polyurethane have their own advantages in terms of manufacturing. Think of polyurethanes more like a combination of rigid plastic and strong rubber. For optimum performance and maximum lifetime, engineering plastics, which are subjected to long-term loading, should have a high creep resistance (ie. Unlike thermoset polyurethane, plastics will tend to remain permanently deformed or even break when stretching, abrasion or impact forces are applied. For reference, “thermoplastic” implies that the material gets soft when heated and hard when cooled. = Acrylonitrile Butadiene Styrene This is a common thermoplastic which is rather easy to bond. Also see . Sure, we all get giddy thinking about the iron and aluminum in our cars. Extruded plastic can have a DOC coating, so you don’t have to paint it. 16% . We live in the future! 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. PVC is usually made softer and more flexible by the addition of plasticizers. However, this is not to say that polyurethane doesn’t have its drawbacks, too. Not only that, they don’t rust or corrode like metal, and they’re lighter and more forgiving on other materials. Thanks for all your answers! And what is the difference? Plus, ABS plastic is very widely used by OEM for body panels. With decades of experience under his belt, he possesses a keen understanding of these materials. In short, “complicated” means “expensive,” which means higher production costs and higher consumer costs. Polyurethane is complicated to produce. 1/4 " abs plastic can be bent using a heat gun to soften it up and then shape it manually.. However, they are not resistant to aromatic and chlorinated hydrocarbons. Gruppe-S: Exterior/Styling: 20: 03-27-2004 12:08 AM That is, unless you heat it to its melting point or freeze it to the point of fracture. Urethane would be like you’re missing a hand and you can inject that hand. Which ABS adhesive is best? But because of its versatility and toughness, polyurethane is often found in areas where abuse is the name of the game. ABS plastics are two-phase systems. Hardness . Well, in the past, fiberglass was used by many automakers to produce lightweight components like hoods, and is still pretty widely available today. Plastics are vital to just about all aspects of society, from consumer products and transportation to heavy manufacturing and infrastructure. 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. Unlike ABS, which is a thermoplastic, polyurethane is a thermosetting plastic. We’re not here to talk about how plastics stack up against other materials commonly used on automobiles. In your car, you can find polyurethane used for interior parts such as the flooring and even bushings in the suspension. Have a question on the chemical resistance of plastics? just very confusing. 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 ...

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. 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. 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). What is polyurethane? But, truthfully, the plastics and polys of the world are what really put the proper finishing touches on a vehicle. The second phase is composed of dispersed polybutadiene particles, which has a layer of SAN grafted onto their surface. But, overall, its characteristics lend it more toward performance than styling. Examples of plastics consists of polyethylene, PVC, nylon and ABS. Longfellow sheds a little light on why this is: “The urethane is going to grow longer.
