Engineering plastics are designed for heavy-duty, superior performance uses that require special features such as shock absorption or chemical resistance. Engineered plastics are considered high-performance plastics explicitly designed to meet more extreme requirements that go beyond the capabilities of most commodity plastics,
While engineering plastics can sometimes cost a little more than other plastics, they boast several significant advantages.
Lightweight
Impact and shock-resistant
Stronger and more resilient than many standard plastics
Can be easily shaped
Excellent machinability
Superb dimensional stability
Resistant to flames, chemicals, and friction
There is a huge variety of engineering plastics, each with unique features. The materials experts at Piedmont Plastics can assist you in selecting the best engineering plastic materials for your project.
Here are some of the most popular types of engineering plastics.
Polycarbonate
Polycarbonate (PC) plastics are a class of thermoplastic polymers with carbonate groups as part of their chemical makeup. A sturdy and resilient material, PC is used in engineering and can come in transparent form. They are simple to mold, thermoform, and process. Polycarbonate is an excellent electrical insulation material with heat resistance and flame retardancy. It is found in a variety of components for electrical and telecommunication systems. PC plastic is also popular in construction for dome lamps, flat or curved windows, and sound insulation.
Acrylonitrile butadiene styrene
As the name suggests, acrylonitrile butadiene styrene (ABS) plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S). ABS is one of the primary materials used for 3D printing. Its qualities include heat resistance, impact resistance, low-temperature resistance, chemical resistance, superb electrical properties, consistent product size, and more. As a result, it’s featured in various products, from containers to automobile parts.
Acrylic / Poly(methyl methacrylate)
Acrylic, the common name for poly(methyl methacrylate) (PMMA), is a prevalent plastic polymer material featuring highly notable transparency, chemical stability, and simple processing. Acrylic enjoys superior weather resistance, high surface hardness, outstanding gloss, high-temperature performance, and excellent processing performance. It can be machined and hot formed. Acrylic has wear resistance comparable to aluminum with solid stability and chemical corrosion resistance.
Polyoxymethylene
Polyoxymethylene (POM) plastic comes in white or black and exhibits excellent hardness, superior rigidity, and high wear resistance. It is commonly used to manufacture gears, bearings, auto parts, machine tools, instrument internals, and other products with skeleton functions.
Polyetherketone
Polyetherketone (PEEK) plastic is a semi-crystalline, high-performance engineering thermoplastic. PEEK boasts high thermal dimensional stability, low flammability, superb chemical resistance, and excellent mechanical properties in a wide temperature range. It is commonly used in the aerospace, aircraft, and automotive industries for structural components requiring high load requirements, such as bushings, gears, shafts, bearings, etc.
