Interior and exterior parts
High-performance reinforced polyamide composites for automobiles have excellent weather resistance, good paint performance and outstanding performance. In order to meet the requirements of internal and external decoration, reinforced polyamide materials should meet the following requirements:
1). High heat resistance, long-term use;
2) excellent combination of rigidity and toughness;
3). It can withstand the constant changes of temperature and humidity and suffer huge strains;
4). Excellent dimensional stability with anti-warping effect;
5). Has a high surface quality and a smooth surface.
Engine peripheral parts
Automotive high-performance reinforced polyamide composites for the manufacture of engine peripheral components, such as intake manifolds, engine covers, etc., can replace traditional metal materials. In order to meet the requirements of the use of peripheral components of the engine, polyamide materials should have the following advantages:
1). Excellent strength and toughness to meet the mechanical properties of structural components;
2). Excellent heat resistance, can be used continuously at temperatures up to 130 ° C;
3). Long-term fatigue resistance, performance after heat aging is good;
4). Excellent dimensional stability with anti-warping effect;
5). Good surface effect, no floating fiber;
6). Good oil resistance and good corrosion resistance.
Automotive Application Overview
PA6 is widely used in automobiles. Automobiles are an important and fast-growing market for plastics. PA6 has good comprehensive performance, low density, easy molding, large design freedom, thermal insulation, and obvious advantages in mold and assembly costs. . PA6 not only has high tensile strength, excellent impact performance, high heat distortion temperature, heat resistance, low friction coefficient, excellent wear resistance, self-lubrication, oil resistance and chemical resistance, and is especially suitable for filling with glass fiber or other materials. Modification, improving material properties and grades to meet the final components and customer needs. At present, there are many kinds of PA6 automobile products, such as radiator box, front grille, heater box, radiator blade, steering column cover, tail light cover, adsorption tank, timing gear cover, fan blade, various gears, radiator water chamber, Air filter housing, intake manifold, control switch, intake duct, vacuum connection tube, airbag, electrical instrument housing, wiper, pump impeller, bearing, bushing, valve seat, door handle, wheel cover, etc. In short, it involves many parts such as automobile engine parts, electrical parts, body parts and airbags. Among them, the amount of parts under the hood of the automobile is the largest, which is due to the miniaturization and light weight development of the automobile, the volume of the engine room is reduced, the temperature is increased, and the parts under the hood are required to be more resistant to high temperatures, and the PA6 can fully achieve the above by modification. Claim. Some industrial analysts believe that PA6 components not only have a protective effect, but also have an aesthetic effect.
