PP, whose full name is polypropylene, is a semi-crystalline thermoplastic polymer produced through the addition polymerization of propylene monomers. It typically appears as a white, waxy solid that is non-toxic, odorless, transparent, and lightweight. With a density ranging from 0.89 to 0.92 g/cm³, it is the lightest thermoplastic resin. Its service temperature range is between -30°C and 140°C.

Application Fields:

Automotive Industry: PP plastic has increasingly become a dominant material for automotive components, making it the most widely used plastic in the automobile sector. Toughened PP is used in bumpers and wheel covers, while reinforced PP is applied in instrument panels, steering wheels, handles, battery casings, and other parts.

Home Appliances: Modified PP plastic is utilized in components such as washing machine tubs, television casings, fan blades, refrigerator liners, and small household appliance housings.
