Tire Manufacturing Styrene Butadiene Rubber/SBR 1712 Rubber Material

Product Description

SBR-1712 is oil-extended copolymer of styrene and butadiene, obtained by cold emulsion polymerization method with the use of rosin and fatty acid soaps. The copolymer is extended with Aromatic Oil - DAE. The polymer is stabilized by staining antioxidant. It provides easier incorporation of filler and maintaining good processability. 

The aromatic oil used is an efficient plasticizer for high molecular 
weight SBR and results in superior physical and processing properties 
compared to other oil-extended rubbers. 

 
Key Features & Advantages:
• Dark brown colour 
• High abrasion resistance 
• Easy vulcanization and stable scorch properties 
• Excellent processability compared to natural rubber)
