Polypropylene (PP) can be used in numerous automotive components. Nowadays, in a typical passenger vehicle, polypropylene plastic components account for more than 60% of the total. The main types of polypropylene automotive components include: bumpers, instrument panels, door trim panels, air conditioning components, battery casings, cooling fans, steering wheels, etc. Among them, the proportions of five components exceed half of the total, and they are all made of polypropylene.
Polyethylene (PE)
Through graft modification and filling of high-density and low-density polyethylene resins, a series of modified polyethylene alloys with good flexibility, weather resistance and coating properties have been developed. Polyethylene is produced by blow molding methods for oil tanks, ventilation pipes, baffles and various types of storage tanks.
ABS Resin
ABS resin, a terpolymer of acrylonitrile, butadiene and styrene, can be used to manufacture external or internal components of automobiles, such as instrument panels, cooling and heating systems, kits, handrails, radiator grille panels; it can also be used to manufacture instrument panel interiors, trunk lids, glove box covers.
In recent years, the growth in the usage of ABS resin in automotive consumption has not been significant. This is mainly because PP and ABS resin are extremely competitive, and ABS also has disadvantages such as poor weather resistance, large color differences and flammability. Therefore, its application in components such as instrument panels and grille panels in automobiles is relatively limited.
Polyamide (PA)
Polyamide is called nylon and has high impact strength, wear resistance, heat resistance, chemical corrosion resistance, lubricity and anti-fouling properties. In automotive structures, increasing the usage of polyamide can also be used in harsh environments around the engine.
