High-weather-resistant ABS plastics and ASA materials have been widely used in commercial vehicles.
If the product needs surface treatment (such as water transfer film, or spraying), use ABS; when surface treatment is not required, use ASA.
The most typical automotive products are electroplated ABS decorative bright strips, such as shift handle head, inner handle, license plate decorative plate, rear spoiler assembly, rearview mirror body, radiator grille body, armrest, and Dashboard.
The largest application areas of ABS resin are automobiles, electronic appliances, and building materials.
Applications in the automotive field include automotive instrument panels, body outer panels, interior panels, steering wheels, sound insulation panels, door locks, bumpers, air ducts, and many other components.
It is also widely used in refrigerators, TVs, washing machines, air conditioners, computers and other industries, copiers, and other electronic equipment. In terms of building materials, ABS pipes, ABS sanitary ware, and ABS decorative panels are widely used in the building materials industry.
ABS plastic has always played an important role in the production of auto parts
Although the appearance of PP in auto parts has shaken the lofty position of ABS in luxury auto parts, ABS cannot be completely replaced by PP. The noble status of ABS is related to excellent performance. Thermoplastic ABS resin is widely regarded as a freely designable engineering material with excellent aesthetics, flow, toughness, dimensional stability, and high heat resistance. ABS is available in a variety of brand options, including low-odor ABS, heat-resistant ABS, frosted ABS, electroplating-grade ABS, and weather-resistant ABS. ABS has a wide range of applications in automotive interior and exterior components. Inside, ABS can be used to make door panels, dashboard trims, glove boxes, central control dashboards, air conditioning outlets, and more. On the outside, ABS is used to make radiator grilles, mirror frames, license plates, and trim labels.
1. Low-odor ABS
The important goal pursued in the low-odor ABS car is to reduce the volatility of the material and improve the air quality in the car, and the low-odor material is one of the goals jointly pursued by the automobile manufacturer and the automobile material manufacturer. Under the condition of indoor air quality of vehicles, low molecular weight organic volatiles in plastics can easily migrate to the surface of plastic products and volatilize into indoor air, thereby reducing the odor to personnel. By choosing the right matrix resin, making the necessary modifications, and controlling the proper process conditions, you will be able to produce ABS materials that meet the automotive manufacturer’s standards.
Low-odor ABS materials are mainly used in automotive interior parts, such as door panels, instrument panel trims, glove boxes, central control dashboards, and air conditioning outlets, especially those that must withstand high temperatures and conduct air.
2. Heat-resistant ABS
For some components that need to withstand high temperatures, it is also necessary to improve the heat resistance of ABS. A common method to improve the heat resistance of ABS is to mix ABS and PC to make ABS/PC alloys.
Heat-resistant ABS is usually used to manufacture heat-resistant components, such as air-conditioning outlets and radiation grills, which can also be made of ABS or ASA. Improving heat resistance, can prevent the deformation of parts and prevent the coating from falling off due to deformation. Due to factors such as large area and impact resistance, PC/ABS alloys are also used. Luxury car fenders are also made of ABS/PC alloys.
3. Matte ABS
Strong light reflections in the car cab can cause driver discomfort and fatigue, which can affect the driver’s vision at night. Therefore, the disappeared ABS has a wide range of applications in automotive cabin components. Because ABS is a high-quality engineering plastic, we chose resin grades with a relatively low finish and broad molecular weight distribution during the modification process. Then choose flake or needle, larger particle size filler. This improves the surface roughness of the product, scatters light, and achieves a quenching effect. . Matting is used in the manufacture of steering wheels, central control dashboards, and other components.
4. Electroplating ABS
Electroplating grade ABS has aesthetics, but in order to obtain better aesthetics, ABS is often required to be electroplated, painted, and other surface decoration treatments. Electroplating grade ABS is obtained by selecting ABS with a specific rubber content and rubber particle size and modifying it to increase its polarity. Mainly used in radiator grilles, decorative labels, and other components.
5. Weather-resistant ABS
Generally, ABS contains double bonds, which are easily decomposed under the action of sunlight and hot oxygen, resulting in pulverization, discoloration, and some loss of mechanical properties. Therefore, weather-resistant ABS is usually used as the outer part. There are several types of ABS, including ACS, AES, and ASA. Among them, ASA is currently the most weather-resistant type, replacing the butadiene rubber of ABS with acrylic rubber. PC/AS/SEBS alloys also have excellent weatherability. Mainly used in the manufacture of automotive exterior parts such as radiator grilles and mirror frames.
The above are the commonly used processes and parts of ABS plastics in automobiles, especially in high-end automobiles, ABS is widely used. So, have you paid attention to these materials on the car in your life?
