KRALEX® 1783 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, contains 27% (37.5 PHR) of extender oil with reduced content of polycyclic aromatics (RAE grade) and is stabilized by a staining antioxidant. KRALEX® 1783 is appropriate for rubber compounds used in the production of car tyres including tyre re-treading, conveyor belts and various technical rubber articles. It is not approved for production of rubber articles coming into contact with foods or drinking water.
