Is polypropylene toxic?

聚丙烯为无毒、无臭、无味的乳白色高结晶的聚合物，不会中毒。聚丙烯无毒、无味，密度小，强度、刚度、硬度耐热性均优于低压聚乙烯，可在100℃左右使用。具有良好的介电性能和高频绝缘性且不受湿度影响，但低温时变脆，不耐磨、易老化。

Polypropylene is a non-toxic, odorless, and tasteless milky white high crystalline polymer that is not toxic. Polypropylene is non-toxic, odorless, with low density, and superior strength, stiffness, hardness, and heat resistance to low-pressure polyethylene. It can be used at around 100 ℃. It has good dielectric properties and high-frequency insulation, and is not affected by humidity, but becomes brittle at low temperatures, is not wear-resistant, and is prone to aging.

聚丙烯广泛应用于服装、毛毯等纤维制品、医疗器械、汽车、自行车、零件、输送管道、化工容器等生产，也用于食品、药品包装。

Polypropylene is widely used in the production of fiber products such as clothing and blankets, medical equipment, automobiles, bicycles, parts, transportation pipelines, chemical containers, and also in food and drug packaging.

聚丙烯的生产工艺 Production process of polypropylene

聚丙烯树脂是四大通用型热塑性树脂（聚乙烯、聚氯乙烯、聚丙烯、聚苯乙烯）之一，以丙烯为原料，乙烯为共聚单体通过聚合反应生产制得。

世界上用于生产聚丙烯的工艺方法按类别划分主要有以下几大类：溶剂法、溶液法，液相本体法（含液相气相组合式）和气相本体法。

Polypropylene resin is one of the four universal thermoplastic resins (polyethylene, polyvinyl chloride, polypropylene, polystyrene), produced through polymerization reaction using propylene as the raw material and ethylene as the comonomer.

The process methods used for producing polypropylene in the world are mainly divided into the following categories: solvent method, solution method, liquid phase bulk method (including liquid phase gas phase combination method), and gas phase bulk method.
