PP (polypropylene) is a kind of thermoplastic resin made by polymerization of propylene. Polypropylene is a kind of milk white high crystalline polymer which is non-toxic, odorless and tasteless. It is one of the lightest varieties of all plastics at present. Polypropylene has excellent mechanical properties and good chemical corrosion resistance.

　　PP plastic has a wide range of applications, such as syringes, infusion bags, blood transfusion tools and other medical equipment; cover, handle, hand wheel and other structural parts; automobile interior parts: plastic injection, infusion bag, blood transfusion tools, etc

　　Seat, armrest, headrest, door inner panel, instrument panel, steering wheel, shock pad; exterior trim:

　　Bumper and fender can also be used to make steering wheel, pedal, trunk, muffler, toolbox and other mechanical parts;

　　PP plastic has good electrical properties, which can make many electrical parts; its excellent corrosion resistance makes it can make many chemical parts, such as pipes, chemical equipment valves and so on. PP plastic can also be used to make general household appliances, such as door and window frame, folding chair, toilet sink, etc. Due to some unsatisfactory properties of PP plastics, the toughness can be improved by dyeing and modification according to customer requirements, cold resistance, weather resistance and dyeing property can be improved, and mechanical properties and heat resistance can be further improved.
