Polypropylene

Polypropylene (Polypropylene, PP for short) is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and is resistant to a variety of organic solvents and acid and alkali corrosion. Polypropylene is the third largest plastic after polyvinyl chloride and polyethylene, and occupies an increasingly important position in the market.

Polypropylene is widely used in various fields such as chemical industry, chemical fiber, construction, light industry, home appliances, packaging, agriculture, national defense, transportation and civil plastic products.

At present, the company's main production of polypropylene grades are T-30S, T-30SF, H40S, PPB-M02FD, also produced polypropylene grades C30S, PPB-M09FD, Y12, Y16, etc.; the company has its own R & D center for the research and development of modified products, production, and has produced grades FDY1500, FD5040, FDY1500, FD5040, 3204FD, PP flame retardant, reinforced PP, automobile bumper material, TPO material, etc. We will research and develop new grades according to the market demand.

The quality of our polypropylene products meets the technical requirements of the standard "Q∕NBFD 001-2022 Polypropylene (PP) Resin", and the following chart shows the requirements of the standard.
