Product Description 产品描述
PJW105 is a low-smoke halogen-free flame-retardant polypropylene insulation compound for automotive cables. It is environmental protection and non-toxic, and has excellent abrasion-resistant property, electrical property and mechanical property. It has simply processability and no need to cross-link. It is an ideal upgrading substitute of 105℃PVC and 105℃irradiation cross-linkable polyolefin insulation compounds. PJW105 can be used as the insulation of automotive cables and communication cables. The highest working temperature is 105℃.
PJW105为汽车电线用无卤阻燃聚丙烯绝缘料，环保无毒，具有优异的耐磨性，电气性能和机械性能，加工性能良好，无需交联，是105℃聚氯乙烯和105℃辐照交联聚烯烃绝缘料的理想升级替代品。主要用于汽车电线的绝缘，也可应用于通讯电缆的绝缘，最高使用温度105℃。
Processing Indicator 加工工艺
Recommend the use of single-screw extruders with L/D= 20～25.
建议使用普通长径比为20-25的单螺杆挤出机进行生产。
