After it was developed in the 60s, polycarbonate (PC) has become a widely used material in the electronics, machinery, and automotive industry thanks to its outstanding mechanical strength, impact-resistance, heat-resistance, and dimensional stability, making it the fastest-growing material in engineering plastics. Modified and strengthened engineering plastic offers exceptional qualities such as heat resistance, mechanical characteristics, dimensional stability, halogen-free, fire-resistance, and impact-resistance. The product can be applied to a variety of backlight module plastic frames. Moreover, engineering plastics offer great formability and mechanical characteristics that are suited to the outer casing of electronics products.
