Is polypropylene toxic?

100

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.

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.

Production process of polypropylene

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.
