Polypropylene, 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. · Acrylonitrile butadiene styrene · Polycarbonate · Polyester · Poly(methyl methacrylate) · Polymer · Nylon · Thermoplastic · Polyolefin · Polytetrafluoroethylene · Polyurethane
