ABS, namely acrylonitrile butadiene styrene copolymer, is an amorphous polymer, which has no obvious melting point, high melt viscosity, poor fluidity, poor thermal stability, poor weather resistance, sensitivity to temperature and shear rate, and moisture absorption tendency. Generally, ABS has a melting point of about 170℃, a decomposition temperature of 260℃, and a large adjustable range of injection temperature. During injection molding, the general temperature is 180℃ to 240℃. Because of the presence of rubber, it absorbs a small amount of water. During production, it needs to be coaxed and dried at 80℃ to 90℃ for 1 to 2 hours. At the same time, due to the presence of rubber, its thermal stability is poor, so it is easy to decompose. During injection molding, the raw materials should not stay in the barrel for too long.
