PP Plastic Granules Raw Material For Air Duct Granule Plastic Industy
Polypropylene PP, also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.
Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance.With a very high melt fluidity, high transparent impact resistance. Good mechanical properties and machining properties.
