What are the engineering plastics used in auto parts?

Answer:

The automotive industry has the largest potential market for POM. POM light weight, easy processing and molding, low production costs, material properties and metal similar. Modified POM wear resistance is very low, rigidity is very strong; very suitable for the manufacture of automotive car pumps, carburetor parts, oil pipelines, power valves, Wan Festival bearings, motor gears, cranks, handles, dashboard, , Electrical switches, belts and other buckets. Manufacture of bushings, gears, sliders and other wear-resistant parts of the modified POM is the strength of these components of the metal wear and tear, reducing the amount of lubricants, and enhance the service life of parts; so you can widely replace copper, zinc and other metal production bearings , Gears, drawers and so on. POM production of automotive components light weight, low noise, easy molding and assembly, so in the automotive industry to obtain more and more widely used.

In the automotive industry, PBT is widely used in the production of bumper, carburetor components, fender, spoiler, spark plug terminal board, oil system parts, dashboard, car ignition, accelerator and clutch pedal and other components. PBT and enhanced PA, PC, POM in the automotive industry in the competition is very intense, PA easy to absorb water, PC heat resistance less than PBT; in the automotive use of taking over, because PBT is better than PA, Will gradually replace PA ,. In the case of relatively high humidity, very humid, due to moisture can easily lead to plasticity reduction, electrical nodes easily lead to corrosion, often can use modified PBT. At 80 ℃, 90% relative humidity, PBT can still be used normally, and the effect is very good.

Engineering plastics for the main role of the car is to make the car lightweight, so as to achieve the purpose of fuel-efficient high-speed. Developed countries will use the amount of plastic cars as a measure of car design and manufacturing level of an important indicator of the level of the world's largest single use of automotive plastics in Germany, the amount of plastic accounted for 15% of the total material. In recent years, China's auto industry has developed rapidly, the current annual output of more than 4 million cars, according to foreign plastic consumption forecast, the automotive industry with modified plastics in more than 500,000 tons, which accounted for a large part of the proportion of engineering plastics, five engineering plastics Performance characteristics are different, the use of the car also have their own emphasis.

Iglidur (R) Engineering plastics bearings in the automotive field The primary requirement for a seat system is low cost. Typically, sheet metal materials or stamping holes for automotive seat systems, as well as cold rolled steel sheets, are of great size However, the minimum clearance is required in the seat system to minimize noise, and in order to solve this contradiction, engineering plastics sliding bearings are increasingly being used.

Nylon is mainly used for automotive engine and engine peripheral components, the main varieties are GFPA6, GFPA66, enhanced flame retardant PA6 and other products. (1) in the automotive engine peripheral components on the application of the engine peripheral components are mainly heating and vibration components, most of its components used in glass fiber reinforced nylon. This is because the nylon has a better overall performance, with glass fiber modified nylon, the main performance has been greatly improved, such as strength, product accuracy, dimensional stability, etc. are greatly improved. In addition, nylon varieties, easy recycling recycling, the price is relatively cheap, these factors contributed to the engine as the engine peripheral components of the ideal choice of materials. The intake manifold is the most typical application of modified nylon in the car. In 1990, BMW AG, the first use of glass fiber reinforced nylon raw materials for the production of intake manifolds in the six-cylinder engine; after the United States Ford and DuPont Company cooperation, common use of glass fiber reinforced PA66 made of intake manifold applications in the V6 engine, after the world's major car companies have to follow up, modified nylon intake manifold has been widely used. (2) in the automotive engine components on the application. Engine cover, engine cover, cylinder head cover and other components are generally modified nylon as the preferred material, compared with the metal material, the cylinder head cover as a case to reduce the quality of 50%, the cost reduced by 30%. In addition to the engine parts, the other parts of the car can also be used to enhance the strength of nylon, such as oil filter, wiper, radiator grille and so on.
