SGS High Impact PP Plastic Granules Wash Basin Polypropylene PP Resin
High Impact PP Plastic Wash Basin Material PP Plastci Granules
Polypropylene, abbreviated as PP, is a colorless, odorless, non-toxic, translucent solid substance. The chemical formula is (C3H6)n, and the density is 0.89~0.91g/cm3. Polypropylene is a thermoplastic synthetic resin with excellent properties. It has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high resistance. Grinding performance, etc.
Application:
PP granules is widely used in the production of woven bags, colored stripe cloth for sunlight shading or covering use, carpet backing (base fabric), container bags, tarpaulin and ropes,cold and hot water pipes,high-impact devices, automotive parts,packaging film and so on.
