Introduction of PP

Polypropylene (PP) is a type of thermoplastic polymer that is widely used in various industries for its versatile properties and affordability. It is a member of the polyolefin family and is derived from the polymerization of propylene monomers. PP is known for its balance of mechanical, chemical, and thermal properties, making it suitable for a wide range of applications.

FAQ About PP Plastic Material

PP’s low density and recyclability contribute to its relatively low environmental impact. However, it’s important to consider end-of-life disposal and recycling processes.

PP comes in various forms, including homopolymer (HPP) and copolymer (CPP), each with its own properties and applications.
