Polypropylene is a thermoplastic made from the combination of propylene monomer. Polypropylene can be classified into 3 types which are homopolymer polypropylene, random copolymer polypropylene and impact copolymer polypropylene. Normally, homopolymer polypropylene has the highest stiffness. Random copolymer polypropylene has higher clarity, good impact resistance and better flexibility. Impact copolymer polypropylene has greater impact strength at low temperature and higher melting points.
Application: Packaging bags, straw, bottles, housewares, caps, food container, toys, healthcare devices, battery casing, automotive parts like fender rear, crates and etc.
