Product description 产品描述
Polypropylene insulation compound is a kind of mixing modification compounds, which regard polypropylene resin as the basic raw material. This product has excellent electricity property, physical and mechanical property, and high-low temperature resistant properties. It not only can be used for the insulation of in-house communication cables, but also for the insulations of high-temperature resistant and anti-fold situations.
聚丙烯绝缘料是以聚丙烯为主的共混改性材料,具有优异的电气性能,物理机械性能和耐高低温性能,可以用于市内通信电缆的绝缘,也可以用于耐高温、耐折场合的绝缘。
 
Processing Indicator 加工工艺
There are smooth surface and extruding quantity if the extruding conditions are not strictly required. If condition permits, please pre-dry the compounds under 80~90℃for 1-2 hours.
PJ105在较宽的挤出条件下,可获得优良的表面光滑度和挤出量。如果条件允许,最好在使用前进行预干燥处理,干燥温度为80~90℃,干燥时间1~2小时。
