聚丙烯塑料高强度

聚丙烯的强度随着乙烯含量的增加而增加。PP的维卡软化温度为150°C。由于高结晶度，该材料的表面硬度和耐划伤性非常好。PP不存在环境应力开裂的问题。通常，通过添加玻璃纤维、金属添加剂或热塑性橡胶对PP进行改性。PP的流量MFR范围为1至40。MFR较低的PP材料具有较好的抗冲击性，但伸长率较低。对于具有相同MFR的材料，共聚物类型的强度高于均聚物类型的强度。由于结晶作用，PP的收缩率很高，一般为1.8~2.5%。收缩方向的均匀性比PE-HD等材料好得多。加入30%的玻璃添加剂可以将收缩率降低到0.7%。均聚物和共聚物PP材料都具有优异的吸湿性、耐酸碱腐蚀性和耐溶解性。然而，它对芳香烃（如苯）溶剂、氯化烃（四氯化碳）溶剂等没有抵抗力。PP不像PE那样在高温下具有抗氧化性

PP Plastic High Strength

Product Details

PP plastic high strength

The strength of PP increases with the increase of ethylene content. The Vicat softening temperature of PP is 150°C. Due to the high crystallinity, the surface rigidity and scratch resistance of this material are very good. PP does not have the problem of environmental stress cracking. Usually, the PP is modified by adding glass fiber, metal additives or thermoplastic rubber. The flow rate MFR of PP ranges from 1 to 40. PP materials with low MFR have better impact resistance but lower elongation strength. For materials with the same MFR, the strength of the copolymer type is higher than that of the homopolymer type. Due to crystallization, the shrinkage rate of PP is quite high, generally 1.8~2.5%. And the direction uniformity of shrinkage is much better than that of PE-HD and other materials. Adding 30% of glass additives can reduce the shrinkage to 0.7%. Both homopolymer and copolymer PP materials have excellent moisture absorption, acid and alkali corrosion resistance, and solubility resistance. However, it has no resistance to aromatic hydrocarbons (such as benzene) solvents, chlorinated hydrocarbons (carbon tetrachloride) solvents, etc. PP does not have oxidation resistance at high temperatures like PE.
