93~ 1 18℃。 ABS plastic, with heat-resistant shape stability of 90, is suitable for parts with strong shape and structure under thermal load. The control range is 93~ 1 18℃, and the product can be increased by 10℃ after annealing. ABS plastic is a terpolymer of acrylonitrile (a), butadiene (b) and styrene (s). The relative contents of the three monomers can be changed at will to make various resins.
