驻级母粒PP抗静电PP防无毒
PP(聚丙烯)树脂分子呈非极性结晶型线型结构，表面活性低，无极性。存在表面印刷性不良;涂布粘接不良;与极性高聚物难以共混;与极性增强纤维、填料难以相容的缺点。和聚合工艺的不同，聚丙烯可以分为等规聚丙烯和无规聚丙烯和间规聚丙烯三种构型。等规聚丙烯易形成结晶态，结晶度高达95%以上，分子量在8-15万之间，赋予他良好的抗热和抗溶剂性；无规聚丙烯在室温下是一种非结晶的、微带粘性的白色蜡状物，分子量低，在3000-10000，结构不规整缺乏内聚力，应用较少。

Chemical and physical properties of giant source PP Y35L: BecauseHOMOPOLYMER PP is very brittle at temperatures above 0C, therefore,many commercial PP materials are tongs with random copolymers of1-4% ethylene or higher ethylene content. The copolymer type PP haslower thermal distortion temperature (100C) , lower transparency,lower gloss and lower rigidity, but higher impact strength. Thestrength of PP increased with the increase of ethylene content. PPdoes not have the problem of environmental stress cracking.Generally, PP is modified by adding glass fiber, metal additive orthermoplastic rubber. The MFR OF PP is in the range of 1 ~ 40. PPWITH LOW MFR had better impact resistance but lower tensilestrength. For the same MFR materials, the strength of Copolymertype is higher than that of homopolymer type. Great Positive SourcePP Y35L mechanical properties: PP tensile strength and rigidity aregood, but poor impact strength, especially low temperature impactresistance. In addition, if there is orientation or stress duringthe molding process, the impact strength will be significantlyreduced. Although the impact strength is poor, after being filledor reinforced, its mechanical properties can compete with theengineering plastics with high cost in many fields. Oh,Shit
