OIL-EXTENDED BUTADIENE-STYRENE RUBBERS

SBR 1712


Rubber SBR 1712 is produced by co-polymerizing of butadiene with styrene and butadiene, in emulsion at a temperature of 5°C, using a mixture of rosin and synthetic-acid soaps as an emulsifier. Rubber is precipitated from latex by salt and acid techniques.
