Product description 產品描述
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。
Processing Indicator 加工工藝
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在較寬的擠出條件下，可獲得優良的表面光滑度和擠出量。如果條件允許，最好在使用前進行預干燥處理，干燥溫度為80~90℃，干燥時間1~2小時。
