PC plastic has outstanding impact strength and creep resistance, high heat resistance, good cold resistance, embrittlement temperature reaches – 100 ℃, bending and tensile strength equivalent to nylon, high elongation, and elastic modulus. | It can be used as gears, worm gears, racks, cams, bearings, spindles, pulleys, transmission chains, nuts, washers, pump impellers, lampshades, containers, shells, covers, etc. |  |
| Polymethyl methacrylate (, acrylic, plexiglass) | It is the best organic synthetic transparent material. PMMA has good chemical stability, weather resistance, good electrical insulation, and easy dyeing. And it is suitable for both hot forming and mechanical processing. |
As a transparent material with excellent performance, PMMA is widely used in various lamps, lighting equipment, optical glass, various instrument dials, housings, dials, optical fibers, commodity advertising windows, billboards, aircraft cockpit glass, bulletproof glass for aircraft and automobiles, various medical, military, architectural glass and other fields. |  |
| Polyoxymethylene (POM) | High tensile strength, impact strength, rigidity, fatigue strength, creep resistance, good dimensional stability, low water absorption, low friction coefficient, and good chemical resistance. Its performance is no less than nylon, but it is a low price. | It can be used as various copper substitute parts for bearings, gears, cams, valves, pipe nuts, pump impellers, small parts of body chassis, automobile dashboards, carburetors, boxes, containers, rods, and spray. |  |
| Polyurethane (PU, also known as Urethane) | PU plastic has the rigidity of plastic and the elasticity of rubber. It has pressure and shock resistance, impact resistance, oil resistance, acid and alkali resistance, and excellent wear resistance. PU series elastomer has superior tensile strength, tear resistance, high elasticity, high-pressure load resistance, wear resistance, and other characteristics. |
It is easy to cut, grind, drill, and perform other processes. It applies to mechanical buffer materials, punch dies, recoil pads, bending, and forming. And it is suitable for the shock-absorbing pads, cushion blocks, and springs of metallurgy, mining, petroleum, automobile, building materials, sports, heavy machinery, large stamping equipment, and for making stamping dies for various metal plates and pipes. |
 |
| Polyether ether ketones (PEEK) | PEEK is an aromatic crystalline thermoplastic polymer material with high mechanical strength, high-temperature resistance, impact resistance, flame retardant, acid and alkali resistance, hydrolysis resistance, abrasion resistance, fatigue resistance, radiation resistance, and good electrical properties. With excellent sliding characteristics, it is suitable for occasions where strictly require low friction washing and wear resistance. |
