Ph of polypropylene
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. Polypropylene … See more Polypropylene is produced by the chain-growth polymerization of propene: The industrial production processes can be grouped into gas phase polymerization, bulk polymerization See more Melting process of polypropylene can be achieved via extrusion and molding.
