Polypropylene is a tough, rigid and crystalline thermoplastic produced from propene (or propylene) monomer. It is a linear hydrocarbon resin. The chemical formula of polypropylene is (C3H6)n. PP is among the cheapest plastics available today.
Molecular Structure of Polypropylene
PP belongs to polyolefin family of polymers and is one of the top three widely used polymers today. Polypropylene has applications both as a plastic and a fiber in:
Automotive Industry
Industrial Applications
Consumer Goods, and
Furniture Market
It has the lowest density among commodity plastics.
