PolyPropylene (PP Chemical)

Polypropylene or PP is a thermoplastic polymer made from the monomer propylene. It is one of the most widely used plastics in the world due to its unique properties such as high chemical resistance, heat resistance, low density and reasonable price.

Chemical structure and properties of polypropylene

The chemical structure of polypropylene is in the form of long, linear chains of carbon and hydrogen atoms. This structure results in the following properties:

High chemical resistance: Polypropylene is resistant to many chemicals such as acids, bases and solvents.
Good thermal resistance: Polypropylene can operate at high temperatures without significant deformation.
Low density: Polypropylene is one of the lightest plastics.
Electrical insulation: Polypropylene is a good electrical insulator.
Fatigue resistance: Polypropylene has good resistance to repetitive stresses.
