聚丙烯是由丙烯聚合而得的热塑性塑料，通常为无色、半透明固体，无臭无毒，密度为0.90 ~ 0.919克/厘米，是最轻的通用塑料，其突出优点是具有在水中耐蒸煮的特性，耐腐蚀，强度、刚性和透明性都比聚乙烯好，缺点是耐低温冲击性差，易老化，但可分别通过改性和添加助剂来加以改进。

聚丙烯由于价格低廉，综合性能良好，容易加工，因此应用比较广泛。特别是近些年来聚丙烯树脂改性技术的迅速发展，使它用途日趋广泛。普通的聚丙烯可以通过共聚改性、交联改性、接枝改性等化学改性方法和物理改性方法来扩大使用范围，在性能上和工程塑料相媲美。

Polypropylene (PP)

Polypropylene is a thermoplastic polymer derived from the polymerization of propylene, usually a colorless, translucent solid, odorless and non-toxic, with a density of 0.90 to 0.919 g/cm. It is the lightest universal plastic and its outstanding advantage is its resistance to water. Cooking characteristics, corrosion resistance, strength, rigidity and transparency are better than polyethylene, the disadvantage is poor low-temperature impact resistance, easy to age, but can be improve by modification and addition of additives.

Polypropylene is widely used due to its low price, good overall performance, and ease of processing. In particular, the rapid development of polypropylene resin modification technology in recent years has made its use increasingly widespread. Ordinary polypropylene can be expanded in the scope of use by chemical modification and physical modification methods such as copolymerization modification, cross linking modification, graft modification, etc., and the performance is comparable to that of engineering plastics.
