Chemical properties of ABS materials

ABS is a graft copolymer of acrylonitrile, butadiene and styrene. Its molecular formula can be written as (C8H8. C4H6. C3H3N) x, but in fact, it is often a mixture of butadiene graft copolymer and acrylonitrile styrene copolymer. Acrylonitrile is 15%~35%, butadiene is 5%~30%, styrene is 40%~60%, the most common proportion of ABS in emulsion method is A:B:S=22:17:61, and the proportion of B in bulk ABS is usually low, about 13%. The molding temperature of ABS plastic is 180-250 ℃, but it's better not to exceed 240 ℃. At this time, the resin will decompose.

(acrylonitrile butadiene styrene copolymer, ABS is acronym of acrylonitrile butadiene styrene) is a thermoplastic polymer structure with high strength, good toughness and easy processing. Also known as ABS resin.

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 low temperature ductility and impact resistance for ABS resin, but too much butadiene will reduce the hardness, luster and fluidity of the resin;

Acrylonitrile provides ABS resin with hardness, heat resistance, acid alkali salt resistance and other chemical corrosion properties;

Styrene provides hardness, processing fluidity and surface finish for ABS resin.
