As a reliable SBR 1712 supplier, we provide ASTM-compliant industrial grade rubber bales with consistent batch quality and stable bulk supply, serving tire manufacturing, industrial rubber goods and footwear industries worldwide.
Superior processing performance: The 37.5phr oil extension gives SBR 1712 stable Mooney viscosity and excellent plasticizing performance, adapting smoothly to mixing, calendering, extrusion and molding processes. It supports high filler loading, reduces production energy consumption and improves overall manufacturing efficiency.
Excellent abrasion & dynamic fatigue resistance: Compared with non-oil-extended general SBR grades, SBR 1712 exhibits better wear resistance, tear strength and flex cracking resistance. It maintains stable load-bearing performance under long-term dynamic working conditions, effectively extending the service life of end products.
High cost-efficiency & blending compatibility: The oil-filled formula lowers unit material cost while retaining balanced physical properties. It can be blended in any proportion with natural rubber, polybutadiene rubber and other elastomers, allowing flexible formula adjustment for different performance and cost targets.
Good thermal & weather aging resistance: Under normal service temperatures, SBR 1712 delivers better heat aging and weather cracking resistance than natural rubber, maintaining stable physical properties in outdoor and medium-temperature industrial scenarios.

FAQ
What are the main applications of SBR 1712?
SBR 1712 is primarily used in tire treads, sidewalls, camelback retreading compounds, rubber conveyor belts, shoe soles, hoses, molded rubber parts and other black industrial rubber products, where balanced abrasion resistance, processability and cost efficiency are required.
What is the difference between SBR 1502 and SBR 1712?
The core differences lie in oil extension and color stability: SBR 1502 is a non-oil-extended, non-staining grade designed for light-colored and colored rubber products, while SBR 1712 is a 37.5phr oil-extended, staining grade with better processability and lower unit cost, intended for black rubber goods such as tire treads and industrial belts.
What is SBR 1712?
SBR 1712 is a cold emulsion-polymerized, oil-extended styrene butadiene rubber (E-SBR) filled with 37.5 phr high aromatic oil. With 22.5–24.5% bound styrene and a staining antioxidant system, it is a cost-effective general-purpose synthetic rubber widely used in tire manufacturing and industrial rubber products for its excellent processability and abrasion resistance.
