Types of plastics for automobiles
With the continuous development of new plastic materials, plastics continue to expand in the field of automotive applications:
Development of plastic functional parts
Brackets, brackets, and multi-function parts are made from glass fiber reinforced thermoplastics (GMT). The application of plastic manufacturing intake manifold can reduce the weight by 40% to 60%, and the surface is smooth, the flow resistance is small, the engine performance can be improved, and it has a certain effect in improving combustion efficiency, reducing fuel consumption and damping and noise reduction. The development of "composite type electrically conductive plastics" in which a conductive filler is incorporated in a matrix polymer and the "conducting polymer compound" in which the plastic itself has electrical conductivity are selected for use in automobile production with high functional properties.
Dashboard, interior system
Many foreign automobile factories use foam polyurethane to make door panels, which not only can reduce weight, strength, sound absorption and safety performance. Polypropylene is widely used in the US automotive market due to its low price. It not only replaces ABS with polypropylene, but also uses polypropylene for interiors of some models. At present, the instrument panels used in China can be divided into hard instrument panels and soft instrument panels. Hard instrument panels are generally injection molded from modified polypropylene and used on economical vehicles. The soft instrument panel is a polyurethane reactive foam molding, usually used in mid- to high-end cars.
In conclusion
The innovative application of plastic materials will be the key point of concern and attention in automobile manufacturing. In addition to relying on innovations in engines and new raw materials, automobiles will rely heavily on plastic technology in the wake of energy shortages and environmental protection. development of. Whoever gets the lead in material selection and application can get more benefits.
