ABS is a copolymer composed of three monomers: acrylonitrile (A), butadiene (B), and styrene (S). It combines the advantages of all three components—acrylonitrile provides chemical resistance and rigidity, butadiene offers impact strength, and styrene contributes gloss and processability. With a melt index ranging from 1 to 30 g/10min, ABS is primarily used in electronics and electrical appliances, automotive, household goods, and industrial building materials.
