Products Description
Polypropylene is a semi-crystalline thermoplastic polymer synthesized through the addition polymerization of propylene monomers. It typically appears as a non-toxic, odorless, white waxy transparent solid. Due to its excellent chemical stability, heat resistance, mechanical properties, and plasticity. Widely used in textile fibers, appliance housings, medical devices, and construction materials.
