Did you know?
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. WebDuring the production of polyethylene (PE), a portion of the ethylene and other hydrocarbon feedstock is lost. The value of the lost feedstock is substantial, ranging from $1 million to …
