聚丙烯PP管/聚丙烯管(又名聚丙烯管材)

    PP管是一种半结晶性资料。它比PE要更坚固而且有更高的熔点。因为均聚物型的PP管温度高于0℃以上时十分脆?因而很多贸易的PP资料是参加1~4%乙烯的无规矩共聚物或更高比率乙烯含量的钳段式共聚物。共聚物型的PP资料有较低的热歪曲温度(100℃)、低通明度、低光泽度、低刚性,然则有有更强的抗冲击强度。PP的活动率MFR局限在1~40。而且缩短率的偏向平均性比PE-HD等资料要好得多。参加30%的玻璃添加剂可以使缩短率降到0.7%。均聚物型和共聚物型的PP资料都具有抗吸湿性、抗酸碱侵蚀性、抗消融性。但是,它对芬芳烃(如苯)溶剂、氯化烃(四氯化碳)溶剂等没有抵当力。PP管也不象PE那样在高温下仍具有抗具氧化性。
   PP pipe is a semi crystalline material. It is more rugged than PE and has a higher melting point. Because the homopolymer PP type tube temperature higher than 0℃very fragile? So many trade information of PP is to join the 1~4% ethylene copolymer without rules or higher ratio of ethylene content clamp copolymers. Copolymer type PP data have lower heat distortion temperature ( 100 ℃), low brightness, low gloss, low rigid, but have a stronger impact strength. The activity of PP MFR in 1~40 rate limitation. And shortening rate bias average data is much better than PE-HD. In 30% glass additives can make the shortening rate down to 0.7%. Homopolymer and copolymer type PP material with excellent moisture resistance, acid and alkali resistance erosion resistance, anti ablation of. However, the aromatic hydrocarbons ( such as benzene solvent ), chlorinated hydrocarbons (CCL ) solvent no resistance. PP don't like PE at high temperatures with antioxidant.
