聚丙烯塑料是具有优良综合性能的聚烯烃塑料,自1957年工业化生产以来,得到迅速、稳定的发展。目前已成为四大热塑性材料之一。聚丙烯是无色、无味、无毒的热塑性塑料。它的分子排列很有规律,具有结晶性。聚丙烯可按分子排列的方式不同,分为等规聚合物,间规聚合物和无规聚合物。目前,国产聚丙烯主要是等规聚合物。 Polypropylene plastic is a polyolefin plastic with excellent overall performance. Since its industrialization in 1957, it has been rapidly and steadily developed. Has become one of the four thermoplastic materials. Polypropylene is a colorless, odorless, non-toxic thermoplastic. Its molecular arrangement is very regular, with crystallinity. Polypropylene molecular arrangements can be different, divided into isotactic polymers, syndiotactic polymers and random polymers. At present, domestic polypropylene is mainly isotactic polymer.
