Polypropylene (PP)
PP is obtained by polymerization of propylene gas under pressure. Polypropylene is a low specific weight wear resistant thermoplastic. High resistance to chemical solvents.
Crystal and translucent structure, 0.90 to 0.91 g/cm3 density, this polymer is one of the lightest thermoplastics. Melting point is 160-164 °C.
Polypropylene generally has three kinds;
1. PPH-polypropylene homopolymer
2. PPIC-polypropylene Block Copolymer
3. PPRC-polypropylene random copolymer
