Product Description
SBR–1502 is a cold, 23.5% styrene SBR polymer made with a mixed–acid
emulsifier, a non-staining stabilizer and a salt–acid coagulation. Provided
that the compounds are formulated and processed correctly, the vulcanizates have very good abrasion , good heat and aging resistance, good
mechanical properties , good electrical properties and good resistance to polar solvents and dilute acids.
