Acrylonitrile-butadiene-styrene copolymer (ABS) is a thermoplastic polymer material with high strength, good toughness and easy processing. ABS is a terpolymer of acrylonitrile, 1,3-butadiene, and styrene. It can perform normally in the environment of -25℃~60℃, and has good formability. The surface of the processed product is smooth and easy to dye and electroplating. And it can be compounded into a blend with a variety of resins. Now mainly used for alloys, plastics.
On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was preliminarily sorted for reference, and acrylonitrile-butadiene-styrene copolymer was included in the list of three types of carcinogens.
performance
Acrylonitrile-butadiene-styrene copolymer (ABS) is a thermoplastic polymer material with high strength, good toughness and easy processing.
Ingredient structure
ABS resin is a graft copolymer composed of three monomers, acrylonitrile, 1,3-butadiene and styrene. Its molecular formula can be written as (C8H8)x·(C4H6)y·(C3H3N)z.
performance change
With the adjustment of the proportion of the three components, the physical properties of the resin will change to a certain extent:
1,3-butadiene provides ABS resin with low temperature ductility and impact resistance, but too much butadiene will reduce the hardness, gloss and fluidity of the resin; acrylonitrile provides ABS resin with hardness, heat resistance, resistance to Chemical corrosion properties such as acid and alkali salts; styrene provides ABS resin with hardness, processing fluidity and product surface finish.
