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.
