ABS Material

(Acrylonitrile - styrene - butadiene copolymer , ABS Acrylonitrile Butadiene Styrene is the first letter of the acronym ) is a high strength, good toughness, easy processing molding of thermoplastic polymer material structure.
Also known as ABS resin .

ABS material is acrylonitrile (Acrylonitrile), 1,3- butadiene (Butadiene), styrene (Styrene) a graft copolymer of the monomers . Its formula can be written as (C8H8 · C4H6 · C3H3N) x, but in fact often the butadiene- containing graft copolymer with acrylonitrile - styrene copolymer mixture , in which the acrylonitrile and 15% to 35% butadiene 5% to 30% , styrene accounted for 40 % to 60% , ABS emulsion method most commonly ratio a: B: S = 22: 17: 61, while the proportion of B in bulk ABS is often more low , about 13 percent . ABS plastic molding temperature is 180-250 ℃, but preferably not more than 240 ℃, at this time the resin will decompose.

With the adjustment of the ratio of the three components , the physical properties of the resin will be some changes: 1,3-butadiene for ABS resins provide low temperature ductility and impact resistance, but too much will reduce the hardness of the resin -butadiene , gloss , and fluidity ; finish to
provide a hardness of ABS resin, styrene , and the fluidity of the processing surface of the product ; acrylonitrile provide ABS resin properties of hardness , heat resistance , acid and salt and other chemical corrosion.
