具有优异的加工性能、机械物理性能、电性能。

ⅱ、PEcompound,basedonPEresin,isproducedandpelletizedwiththedoublecorrugatedscrew,inwhichvariousadditivesareadded.ThecompoundisaccordingtoGB15065-94andIEC60502.Thecompoundhasoutstandingperformancesofprocessing,physical,mechanicalandelectricalproperties.

3、加工工艺

聚乙烯电缆料最好在长径比（L/D为25或25以上的塑料挤出机上挤出加工,建议在使用前进行预干燥（除ZPE,最高干燥温度为100℃。

推荐挤出机各区点设定温度（℃如下:

ⅲ、Processing:
