WebApr 8, 2024 · Polypropylene, or polypropene, is a form of polypropylene. Polypropylene plastic is a thermoplastic polymer that can be used for a range of purposes. It is made from monomer propylene via a chain-growth polymerization process. Polypropylene plastic is a crystalline thermoplastic that is commonly used in consumer items such as packaging … The Young's modulus of PP is between 1300 and 1800 N/mm². Polypropylene is normally tough and flexible, especially when copolymerized with ethylene. This allows polypropylene to be used as an engineering plastic, competing with materials such as acrylonitrile butadiene styrene (ABS). See more Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.
