Non Woven Fabrics Raw Material High Speed Spinning PP Plastic Granules
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.
