ABS resin is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It is also easy to process, product size is stable, and good surface gloss. It is easy to paint and dye. It can also be used for secondary processing such as metal spraying, electroplating, welding, hot pressing and bonding. It is widely used in machinery, automobile and electronics Electrical appliances, instrumentation, textile and construction industries, is a widely used thermoplastic engineering plastics. Acrylonitrile butadiene styrene copolymer is a terpolymer composed of acrylonitrile, butadiene and styrene. Its English name is acrylonitrile – butadiene – styrene copolymer, abbreviated as ABS. ABS is usually light yellow or milky white granular non crystalline resin. ABS is one of the most widely used engineering plastics.
