Polypropylene(PS) injection molding material , is a thermoplastic addition polymer made by combining several propylene monomers.
It is used in a variety of applications to include packaging for consumer products, plastic parts for various industries including the automotive industry, special devices like living hinges, and textiles.
Elasticity and Toughness
Polypropylene has poor resistance to chlorinated solvents and aromatics.
Polypropylene has a relatively slippery surface which can make it a possible substitute for plastics like Acetal (POM) in low friction applications like gears or for use as a contact point for furniture.
