Material Notes:

Description: SBR 1778 is an oil extended cold polymerization SBR with 37.5 parts of discoloring paraffinic/naphthenic oil and light colored high molecular weight styrene-butadiene copolymer of 23.5% bound styrene. SBR 1778 combines the physical properties of oil extended polymers with the light color properties of naphthenic oil.Applications: SBR 1778 can be used to hose, conveyor belt, tire and other industrial products for the light colored goods.CAS No: 9003-55-8Information provided by LG Chemical
