Polypropylene (PP for short) is a semi-crystalline thermoplastic (a thermoplastic resin made by polymerization of propylene) with high-impact resistance, strong mechanical properties, and resistance to a variety of organic solvents and acid and alkali corrosion. It has a wide range of applications in the industry and is one of the common polymer materials.
Non-toxic, tasteless, low density, strength, rigidity, hardness, and heat resistance are better than low-pressure polyethylene, can be used at about 100 ℃. It has good dielectric properties and high-frequency insulation and is not affected by humidity, but it becomes brittle at low temperatures, is not wear-resistant, and is easy to age.
Mainly used in the production of various long and short polypropylene fibers, used in the production of polypropylene woven bags, packaging bags, injection molding products, etc. Used in the production of flame-retardant parts for electrical appliances, telecommunications, lighting, lighting equipment, and televisions.
