Where are the new plastics applications in the automotive industry?
In fact, exterior parts and structural parts of automobile is also gradually "plastic steel", so as to realize the lightweight. The traditional iron and steel materials such as automotive bumper has been replaced by the general engineering plastics, PC/PBT materials, high-grade cars, while in the low-end cars reinforced by PP material; for example, the car doors and trim and triangle in the past by the iron and steel manufacturing, now uses ASA weathering material or PC/ASA material to replace. It is believed that with the development of automobile safety, comfort and light energy saving, the application of engineering plastics in automobiles will be more and more.
Automotive interior materials generally have a matte requirements, so favorable for reducing the visual fatigue of the driver, so as to improve driving safety. The common materials are required for processing or spray matte, matte paint, or in the material adding matte agent was modified to meet the requirements of the interior. PA/ABS alloy itself does not need to add a matte agent, you can bring a special surface soft matte effect. It combines the impact properties of PA with excellent chemical corrosion resistance, thermal stability and ABS good dimensional stability, low temperature, and crystalline materials combined with amorphous materials makes PA/ABS obtain good damping and sound absorption performance, which is very suitable for automotive interior applications. Kumhosunny (Kumhosunny) in 2004 with the Citroen Automobile Company needs to develop a PA/ABS alloy, the material has been applied to the surrounding parts of the automobile dashboard, such as control panel, dashboard cover, air outlet etc.
Dashboard is an important part of the car interior. It is safe, comfortable, functional and decorative in one of the parts made of plastic material (substituted metal material) can reduce weight, reduce the cost, improve the design flexibility and parts integration, improve safety. At present, the plastic materials used in the dashboard of passenger cars are mainly PP+GF, ABS, PC/ABS, MPPO/GF, SMA/GF and so on. In recent years, LFT (long glass fiber reinforced products) have also begun to be used in medium-sized cars, such as Ford, C307, etc.. But the dashboard materials of middle and high grade cars mainly use PC/ABS, SMA/GF and other high-end materials. For example, SGM 710, 618 models, SVW B5GP and B6GP cars with high heat resistance, hydrolysis resistance, low odor and volatilization of PC/ABS material as dashboard material; SGM 18, 201 models are using SMA/GF material as dashboard material.
At present, the application of engineering plastics in automobiles mainly includes interior parts, outer parts and functional structures.
Plastic applications in the automotive industry are numerous, indeed very fire.
