What is Polypropylene (PP)?

Polypropylene (PP) is a type of polymer that is made from monomers called propylene. It is a synthetic polymer that is known for its excellent mechanical and thermal properties, as well as its good chemical resistance.

Polypropylene is a semi-crystalline polymer that has a high melting temperature and a high modulus of elasticity. It has good wear resistance and low coefficient of friction, making it an excellent choice for use in applications where high strength and low friction are required. It is also resistant to a wide range of chemicals, including acids, bases, and organic solvents.

Polypropylene is a versatile material that is used in a wide range of applications, including the aerospace, automotive, and electronics industries. It is also used in the production of seals, gaskets, and other sealing products, due to its excellent chemical resistance and low coefficient of friction.
