Engineering Plastics has wild application in various industries, here list 5 application in automotive plastic parts:

1. Nylon material (PA)

Nylon is mainly used in automobile engines and their peripheral parts. The main varieties are GFPA6, GFPA66, reinforced flame-retardant PA6 and other products.

Application 1 in the peripheral parts of automobile engine: Since the peripheral parts of the engine are mainly heating and vibrating parts, most of the materials used in the parts are glass fiber reinforced nylon. This is because nylon has good comprehensive properties, and the main properties of nylon modified with glass fiber have been greatly improved, such as strength, product precision, and dimensional stability. In addition, nylon has many varieties, is easy to recycle, and is relatively cheap. These factors make nylon an ideal material for engine peripheral parts. The intake manifold is the most typical application of modified nylon materials in the automotive field. In 1990, the German BMW Motor Company first applied the intake manifold made of glass fiber reinforced nylon to the six-cylinder engine. Afterwards, the intake manifold made of glass fiber reinforced PA66 by Ford of the United States was applied to the V6 engine, followed by major automobile companies in the world, and the modified nylon intake manifold was widely used.

Application 2 on automobile engine parts: Engine cover, engine decorative cover, cylinder head cover and other parts generally use modified nylon as the preferred material. Compared with metal materials, taking the cylinder head cover as an example, the mass is reduced by 50%. 30% reduction in cost. In addition to engine parts, reinforced nylon can also be used in other stressed parts of the car, such as oil filters, wipers, radiator grilles, etc.

2. Polyester material (PBT)

In the field of automobile manufacturing, PBT is widely used in the production of automobile parts such as bumpers, carburetor components, fenders, spoilers, spark plug terminal boards, fuel supply system parts, instrument panels, automobile igniters, accelerators and clutch pedals. part. The competition between PBT and enhanced PA, PC, and POM in the automobile manufacturing industry is very fierce. PA is easy to absorb water, and the heat resistance and drug resistance of PC are not as good as PBT. In terms of automotive applications, PBT will gradually replace PA due to its better water absorption resistance than PA. In the case of high relative humidity and very humid conditions, since moisture can easily cause plasticity to decrease, and electrical nodes are likely to cause corrosion, modified PBT can often be used. At 80°C and 90% relative humidity, PBT can still be used normally, and the effect is very good.

3. Polyoxymethylene material (POM)

The automotive industry is the largest potential market for POM materials. POM has the advantages of light weight, high hardness, wear resistance, creep resistance, and chemical corrosion resistance. It is very suitable for the manufacture of automobile pumps, carburetor parts, oil pipelines, power valves, universal joint bearings, motor gears, cranks, and handles. , instrument panel, car window lift device, electric switch, seat belt buckle, etc., especially wear-resistant parts such as sliders are the strengths of modified POM. These parts have little wear on metal, which reduces the amount of lubricating oil and enhances the use of parts. life.

4. Polycarbonate material (PC)

Due to its excellent heat resistance, impact resistance, rigidity and good processing fluidity, modified PC is mainly used in exterior and interior parts of automobiles, parts around instrument panels, antifreeze panels, door handles, Plates, brackets, steering column covers, decorative panels, air-conditioning system parts, lamp parts and other auto parts.
