In the development environment of "plastics instead of steel" and lightweight automobiles, the automobile manufacturing industry will use more plastics as materials for production creation. In a car, many parts and components have plastic.

Polypropylene (pp)

In typical passenger cars, pp plastic parts account for more than 60. The main varieties of pp auto parts are: bumpers, battery shells, instrument panels, door trim panels, steering wheels, etc.

Polyethylene (pe)

Through grafting modification and filling toughening modification of high-density pe and low-density pe resins, a series of modified pe alloy materials with flexibility, weather resistance and coating performance are obtained. pe materials mainly use blow molding methods to produce fuel tanks, vent pipes, baffles, and various storage tanks.

ABS resin

It is a terpolymer of three monomers of acrylonitrile, butadiene and styrene. It can be used to make exterior or interior parts of automobiles, such as instrument housings, refrigeration and heating systems, tool boxes, armrests, radiator grids, and dashboards Skin, luggage compartment, glove compartment cover, etc.

Polyamide (pa)

Commonly known as nylon, it has high impact resistance, friction and abrasion resistance, heat resistance, chemical resistance, lubricity and dyeing properties.

pa can be used in harsh environments around car engines.

Polyoxymethylene (pom)

It has excellent friction and abrasion resistance, long-term sliding properties, molding fluidity, beautiful surface, and gloss properties. It is also suitable for insert molding. Polyoxymethylene type three-layer composite materials are widely used in automobile chassis bushings.
