Poly (styrene-butadiene-styrene) or sbs, is a hard rubber that's used to modify asphalt, to make soles of shoes, tire treads, and other places where durability is important it's a type of copolymer called a block copolymer.

Other styrene consumption is for the production of acrylonitrile-butadiene-styrene (abs) and styrene-acrylonitrile (san) resins (16%), styrene-butadiene (s/b) copolymer latexes (6%) and unsaturated polyester, accounting for an additional 6% of world styrene demand, while sbr and sbr latexes production accounted for 4% of world demand. Engineering polymers our product range includes a wide range of ethylene vinyl-acetate copolymer, nylon 6, glass filled nylon, nylon 66, acrylonitrile butadiene styrene and polycarbonate material request callback. Over 95% of butadiene is produced as a by-product of ethylene production from steam crackers the crude c4 stream isolated from the steam cracking process is fed to butadiene extraction units, where butadiene is separated from the other c4s by extractive distillation. Gip can recommend or develop polymer products based on performance required our technical representative with seasoned expertise in polymer + processing can provide consulting services to offer solutions aimed at boosting performance efficiency + cost. Production of 1,3 butadiene without the need for olefin cracker c4 crude oil streams olefin cracker c4 streams will decrease in availability as the trend towards lighter feedstock increases.
