Is PC harder than abs? ABS is harder than PC. But for light, PC is better than ABS. The performance of ABS is between general-purpose plastics and engineering plastics, with excellent liquidity and relatively low price, so it is widely used. However, its thermal resistance and Weather fastness is poor, and its mechanical properties are not ideal, so its application is limited. PC is the best impact-resistant plastic variety. PC has outstanding impact toughness and creep resistance properties, high thermal resistance, good cold resistance, embrittlement temperature of -100°C, bending and tensile strength equivalent to nylon, and high elongation And elastic modulus, good dimensional stability, abrasion resistance equivalent to nylon, and a certain degree of corrosion resistance. The price is more expensive than ABS. There are many manufactures who doped ABS but claimed to be PC masks. So what is the harm of adding ABS to the mask of the led lighting. The loss o…
