HDPE Nylon Round Bar

Nylon, a polyimide resin, is a light yet tough thermoplastic material. Its density is approximately. 041 lb./cu.in. It is a tough, resilient material with a low coefficient of friction abrasion tests show that Nylon loses less material than do many metals, other plastics, and hard rubber. It can deform under load, then return to its original shape. Nylon retains its impact strength over a wide range of temperatures (-60° to 400°F). It has good resistance to most chemicals. It can be easily machined on most standard metal working machines, power hacksaws, band saws, or circular saws. It is desirable to use a saw with a coarse tooth blade.


PTFE has the highest melting point and is capable of continued service at -180-260 C. PTFE is a melt processible resin capable of continued service at 204 C. PTFE products are used as gasket and packing materials in chemical processing equipment; as electrical insulation for maximum reliability; and in bearings, seals, piston rings and other mechanical applications, especially those require anti-stick characteristics. PTFE has excellent thermal and electrical insulation properties. It has a low coefficient of friction.


The plastics most frequently used in mechanical and apparatus engineering are the semi crystalline plastics PA, POM, PET (crystalline) and their modifications. Their good mechanical stability and excellent slide and wear properties make them suitable for a wide variety of uses. A vast number of modified variants enable optimum solutions to be found for the most widely differing requirements
