Polypropylene

Polypropylene is a widely used, semi-crystalline material. It has been extensively compounded to provide a wide range of properties at a wide range of costs. In general, polypropylene is a low temperature material with excellent chemical resistance. It has no known solvent at 73 F.

Polypropylene is difficult to mold to extremely close tolerances.
