本描述：
PP是一种性能优良的热塑性合成树脂,它是一种高密度、无侧链、高结晶度的线性聚合物，具有比重小,无毒,易加工,抗冲击强度,抗挠曲性以及电绝缘性好等优点.未着色时呈白色半透明，蜡状。密度小,强度刚度,可在100度左右使用.具有良好的介电性能(是指高分子聚合物在电场作用下，表现出对静电能的储存和损耗的性质，通常用介电常数和介电损耗来表示)。和高频绝缘性.不受湿度影响,但低温时变脆,不耐模易老化.适于制作一般机械零件,耐腐蚀零件和绝缘零件.
Purpose:
Common pots, barrels, furniture, film, woven bags, bottle caps, carbumpers, etc. PP is a crystalline polymer with a distinct meltingpoint. It can melt at 173 ~C and decompose at 300 ~C, and decomposeat 360 ~C. Therefore, during injection molding, the temperature ishigh. The adjustable range is large. When injection moulding, thetemperature is generally 190 - 240 C. Polypropylene can also beused as a cleaning agent for other easily decomposed rawmaterials
