Applications of Styrene Butadiene Rubber (SBR1712) in Industrial Manufacturing

Styrene Butadiene Rubber (SBR1712) is a widely adopted synthetic rubber used in various heavy and light industries. As a direct manufacturer, we supply SBR1712 for core downstream applications requiring stringent quality, process compatibility, and end-product performance. Below, we present structured industrial application scenarios derived from real-world practice.

1. Passenger Car Tire Manufacturing

Automotive tire plants integrate SBR1712 in tire tread formulations to enhance abrasion resistance and provide balanced grip under varying temperatures. Compounders select SBR1712 for controlled molecular weight and stabilizer content, ensuring compatibility with natural rubber, carbon black, and silica. Production lines operate continuous mixing with tight tolerance on batch homogeneity, supporting precise curing cycles and sidewall performance. Finished tires undergo rigorous dynamic and endurance testing per automaker requirements before shipment.

2. Conveyor Belt and Industrial Rubber Sheet Manufacturing

Heavy industrial sites rely on SBR1712 for the production of high-strength conveyor belts and flat rubber sheets. Blending with other synthetic elastomers and reinforcing agents, factory batches target high abrasion, tear strength, and processability on calenders. The material’s heat-aging stability suits mining and logistics facilities demanding consistent mechanical integrity under load. QC teams perform batch traceability for critical infrastructure applications requiring extended operational lifespans.

• General-purpose industrial rubber mats
• Impact-absorbing lagging covers
• Wear-resistant lining sheets

3. Footwear Soling and Rubber Shoe Component Production

Footwear manufacturers use SBR1712 as a cost-efficient elastomer base for molded shoe soles and rubber boots. By adjusting blend ratios with natural rubber or plasticizers, production teams achieve a balance of flexibility, slip resistance, and abrasion resistance tuned to each footwear range. Injection and compression molding methods require SBR with consistent viscosity and limited gel content to ensure defect-free finish and batch uniformity in mass production environments.

Downstream process integration

• Integrated into bulk compounding with fillers and pigments
• Processed via injection, compression, or transfer moulding depending on mold and article type
• Finishing and surface treatment post vulcanization as required

Final product types

• Molded shoe soles (both mono- and dual-density)
• Safety footwear outsoles
• Waterproof rubber boots and galoshes
• Midsole and heel cushions

4. Automotive Rubber Hose and Sealing Component Manufacturing

SBR1712 is specified for under-hood hoses and sealing profiles in car manufacturing due to its balance of elasticity, weather resistance, and bondability with textile or metal inserts. Automotive part suppliers formulate hose and gasket compounds to meet OEM material lists and certification protocols. Controlling blend viscosity and mooney values ensures extrusion stability and minimizes dimensional tolerance drift across large batch productions. Resistance to glycol, water, and road salt remains essential for under-hood and body sealing applications.

5. Industrial Roll and Printing Blanket Fabrication

Factories producing rollers for steel plants, printing presses, and paper mills employ SBR1712 for its compression set resistance and dynamic fatigue strength. SBR-based rubber covers bond well to metal or textile cores, resisting abrasive wear and ink or solvent exposure. Manufacturing teams closely control cure time, nip hardness, and layer adhesion parameters to deliver consistent roll performance over prolonged duty cycles. Certification bodies require batch samples for destructive and non-destructive QC inspection.
