聚丙烯PP管/聚丙烯管(又名聚丙烯管材)

    PP管是一種半結晶性資料。它比PE要更堅固而且有更高的熔點。因為均聚物型的PP管溫度高于0℃以上時十分脆?因而很多貿易的PP資料是參加1~4%乙烯的無規矩共聚物或更高比率乙烯含量的鉗段式共聚物。共聚物型的PP資料有較低的熱歪曲溫度(100℃)、低通明度、低光澤度、低剛性,然則有有更強的抗沖擊強度。PP的活動率MFR局限在1~40。而且縮短率的偏向平均性比PE-HD等資料要好得多。參加30%的玻璃添加劑可以使縮短率降到0.7%。均聚物型和共聚物型的PP資料都具有抗吸濕性、抗酸堿侵蝕性、抗消融性。但是,它對芬芳烴(如苯)溶劑、氯化烴(四氯化碳)溶劑等沒有抵當力。PP管也不象PE那樣在高溫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.
