Polypropylene (PP)

Polypropylene (PP) is a linear hydrocarbon polymer, expressed as CnH2n. PP, like polyethylene and polybutene (PB), is a polyolefin or saturated polymer. Polypropylene is one of those most versatile polymers available with applications, both as a plastic and as a fiber, in virtually all of the plastics end-use markets.

Polypropylene’s unique qualities and ability to adapt make it suitable for an extremely wide range of applications. Its chemical resistance makes it useful as a material for solvent containers. Living hinges are created from polypropylene plastic thanks to its shape retention and fatigue resistance properties. Electronic components also use polypropylene for electrical insulation. Other very common uses for polypropylene include flexible packaging, rigid packaging, piping, food containers, clear plastic bags, ropes, carpets and concrete reinforcement. Polypropylene fibers are used in clothing and diapers.
