pp科莱恩驻极母粒添加2%

pp性能和优点：

pp树脂为白色蜡状物固体，它的密度很低，在0.89 一0.92g /cm3 之间，pp是塑料材料中除4--1-烯（p4mp ）之外轻的品种。聚丙烯综合性能良好，原料来源丰富，生产工艺简单，而且价格低廉。pp的力学性能与聚乙烯相比，其强度、刚度和硬度都比较高，光泽性也好。但在塑料材料中仍属于偏低的。如果需要高强度时，可选用高结晶聚丙烯或填充、增强聚丙烯。pp的冲击强度对温度的依赖性很大，其冲击强度较低，特别是低温冲击强度低。pp的冲击强度还与分子量、结晶度、结晶尺寸等因素有关。

2. pp hashigh crystallinity and regular structure, therefore it hasexcellent mechanical properties, its strength and hardness,elasticity are higher than dhpe, but at room temperature and lowtemperature, because of its high molecular structure regularity,the impact strength is poor, when the molecular weight increases,the impact strength also increases, but the processing performancebecomes worse, polypropylene also has excellent bending fatigueresistance, its products can be bent 106 times at room temperaturewithout damage. 3. pp has good heat resistance, melting point at164170 degrees, the product can be more than 100 degreestemperature disinfection, in the case of no external force, 150degrees do not deformation, embrittlement temperature-35 degrees,in less than-35 degrees will occur embrittlement. 4. pp hasexcellentuency insulation performance, because it almostdoes not absorb water, insulation performance is not affected byhumidity, it has high dielectric, and with the rise of temperature,it can be used to make heating electrical insulation paperproducts.
