SYNTHOS Kralex® 1712 Styrene Butadiene Rubber
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	KRALEX® 1712 is a standard grade of oil extended styrene butadiene rubber. It is produced by a technology of cold emulsion polymerisation based on soaps of rosin and fatty acids and contains 23.5% of chemically bounded styrene. It is coagulated by a system of acid and organic coagulant, contains 27% (37 PHR) of aromatic extender oil (DAE grade) and is stabilized by a staining antioxidant. KRALEX® 1712 is appropriate for rubber compounds used in the production of car tires and inner tubes, including tire re-trading, conveyor belts, footwear and various technical rubber articles. It is not approved for production of rubber articles coming into contact with foods or drinking water. Synthos was formerly known as Kaucuk. All information provided by Synthos.
