Polypropylene (PP) is a thermoplastic polymer obtained from the polymerization of propylene. It is one of the most widely used polymers due to its combination of mechanical and chemical properties, as well as its ease of processing and low cost. PP is available in various variants, including homopolymer PP, copolymer PP, and random copolymer PP, each with specific characteristics.
