SBR-1712 Description

SBR-1712 is staining type cold SBR, extended with 27.5 part of highly aromatic oil. Provided that the compounds are formulated and processed correctly, the vulcanized SBR–1712 has very good abrasion, good electrical properties and good resistance to polar solvents and dilute acids .

SBR-1712 Applications

The SBR-1712 used for the production of tires, high quality technical rubber goods, moulded and extruded mechanical rubber goods and other industrial products where colour and staining are not decisive factors.
