polypropylene
Sign in to savePolypropylene (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.
AI overview
Polypropylene is a lightweight plastic made by linking together molecules of a chemical called propylene, and it can be melted and reshaped multiple times without losing its properties. It matters because it's used in countless everyday products and applications, making it one of the most versatile plastics in modern manufacturing.

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 belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance.
