ABS
Key words:
ABS material is a grafted copolymer of three monomers: acrylonitrile, 1,3-butadiene (Butadiene) and styrene. Its molecular formula can be written as (C8H8· C4H6· C3H3N)x, but in fact it is often a mixture of butadiene-containing grafted copolymer and acrylonitrile-styrene copolymer, of which acrylonitrile accounts for 15% ~ 35%, butadiene accounts for 5% ~ 30%, styrene accounts for 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 often lower, about 13%. The molding temperature of ABS plastic is 180-250 °C, but it is best not to exceed 240 °C, at which time the resin will decompose.
