Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of
applications including packaging, textiles, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components. Most commercial polypropylene has an intermediate level of crystallinity between that of low-density polyethylene (LDPE) and high-density polyethylene (HDPE).
Polypropylene is normally tough and flexible, this allows this material to be used as an engineering plastic, competing with materials such as ABS. Polypropylene is reasonably economical, and can be made translucent when uncolored but is not as readily made transparent as polystyrene, acrylic, orcertain other plastics. Polypropylene has good resistance to fatigue.

Usual uses

Margarine tubs, microwaveable meal trays, carpets, wall coverings, parts for automotive and consumer products. Flexible packaging (food and confectioneries, tobacco, clothing ...), rigid packaging (crates, bottles, pots ...), caps and closures for beverage and cosmetic applications, film tapes, syringes, housewares, furniture, appliances, luggage, toys.
