Polypropylene is known for its good mechanical properties, heat resistance, and chemical resistance. In addition, PP has the highest flexural modulus of the polyolefins, is among the lightest of the engineering thermoplastics (SG=0.90), and has excellent moisture resistance.
Homopolymers exhibit high stiffness, Copolymers have impact and ductility advantages, while random copolymers display good clarity and have a low melting point.
Polypropylene is a thermoplastic polymer and one of the most commonly produced plastics in the world. There are two types of polypropylene; homopolymers and copolymers. In each category there are a number of products offering different properties which allow for a wide range of uses. Some of the properties polypropylene offers are chemical resistance, elasticity and toughness, fatigue resistance, insulation and transmissivity. Polypropylene is used for caps and closures, appliances, furniture, housewares, packaging, films, fibers or automobiles.
