                                                            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.
                                                            聚丙烯絕緣料是以聚丙烯為主的共混改性材料,具有優異的電氣性能,物理機械性能和耐高低溫性能,可以用于市內通信電纜的絕緣,也可以用于耐高溫、耐折場合的絕緣。
