Product Description
KER® 1502 is a standard grade of styrene-butadiene rubber. It is produced by a technology of cold emulsion copolymerization based on soaps of rosin and fatty acids and contains 23.5% of chemically bonded styrene. It is coagulated by a system of acid and synthetic coagulant, does not contain extender oil and is stabilized by a nonstaining antioxidant.

KER® 1502 is used for production of tyres, coloured rubber articles to be used in automotive, footwear and electrical industry as well as for production of hard rubbers and ebonites.
Synthos Dwory Sp. z o.o. holds certificate issued by ISEGA approving application of KER® 1502 for manufacture of goods intended to come in contact with foodstuffs in accordance with BfR and FDA requirements.
