ABS is a terpolymer of three monomers: acrylonitrileA), butadiene (B) and styrene (S). The relative content of the three monomers can be changed at will to make various resins. ABS plastic has the common properties of three components. A makes it resistant to chemical corrosion, heat resistance, and has a certain surface hardness, B makes it have high elasticity and toughness, and S makes it have the processing and molding characteristic of thermoplastics and improve electrical properties. performance. Therefore, ABS plastic is a kind of "tough, hard and rigid" material with easy-to-obtain raw materials, good comprehensive performance, low price and wide range of uses.
