[0002] ABS plastic is a ternary copolymer of acrylonitrile (A), butadiene (B), and styrene (S). The relative content of the three monomers can be changed arbitrarily to make various resins. ABS has the common properties of the three components. A makes it resistant to chemical corrosion and heat, and has a certain surface hardness, B makes it highly elastic and tough, and S makes it have the processing and molding characteristics of thermoplastics and improves electrical properties. Therefore, ABS plastic is a "tough, hard, and rigid" material with easy-to-obtain raw materials, good comprehensive properties, low price, and a wide range of uses.
