In the past, glass and metal materials were used as the materials for car lights, but due to the poor comprehensive performance of both, the processing is more complex. Choosing engineering plastic as the material for car lights has good processing performance, strong plasticity, good impact strength, light weight, low density, and can also make the car lights more flexible and versatile in design, with a style that tends to be modern and contemporary.
Why choose plastic for car lights
At present, the plastic materials used for car lights in China mainly include PC, PP, ABS, PMMA, and a few other plastic materials. Plastic has the advantages of light weight, corrosion resistance, good impact resistance, high transparency, good insulation, low thermal conductivity, good mechanical properties, strong plasticity, and molding processing, and is increasingly being used in various fields.
The application of modified plastics in car lights
Polycarbonate (PC) is a polymer containing carbonate groups in its molecular chain. Polycarbonate is known as bulletproof adhesive due to its excellent mechanical properties. It has the characteristics of high mechanical strength, wide temperature range, good electrical insulation performance (but unchanged arc resistance), good dimensional stability, and good transparency. Widely used in car lights and other fields.
PC accounts for about 50% of plastic materials in front headlights, mainly used in the interior mirrors, aluminum plated decorative parts, and exterior light distribution mirrors of headlights and fog lights. The bonding strength between PC and aluminum coating is very good, and aluminum can be directly plated on PC substrate.
The most commonly used material for injection molded LED car lights
The main components of car lights are composed of reflectors, lenses, shells, light sources, electronic circuits, and installation accessories. Currently, the plastic materials used for car lights in China mainly include PC, PP, ABS, PMMA, and a few other plastic materials.
