聚乙烯异形件：聚乙烯异形件是热塑性工程塑料。它综合了所有塑料的优越性能，具有耐磨损、耐冲击、耐化学腐蚀、自身润滑、抗低温磨损系数小、重量轻、吸能、耐老化、阻燃、抗静电等优良性能。
特点：
1:高耐磨
2:摩擦阻力小.
3;自行润滑.(不需任何润滑油)
4:具有抗冲击性.
5:使用温度范围-200~+80℃.
6:具有减震作用.
7:在潮湿环境下不易受潮.
8:具有高的抗化学性能.
9:有抗腐蚀性
Polyethylene has many names. The most common are HDPE, LDPE, anduhmw The difference has to with the molecular weight and branching which is when a monomer or atom is replaced by a longer chain of polymers (a long repeating chain of atoms).
