Styrene Butadiene Rubber

Styrene Butadiene Rubber (SBR) is a general-purpose synthetic rubber known for good abrasion resistance, processing performance and cost efficiency. It is widely used where balanced mechanical properties and reliable processing are more important than strong resistance to oils or fuels.

Polykem supplies different SBR grades for tire, footwear and industrial rubber production, with grade matching support based on application, Mooney viscosity, oil extension and processing requirements. Contact Polykem for SBR grade information, free samples and quotation support.

Product Feature

Abrasion Resistance

SBR withstands repeated friction and wear, supporting use in tires, footwear and industrial rubber products.

Balanced Mechanical Properties

It provides a practical combination of strength, elasticity and flexibility for general-purpose rubber applications.

Processing Versatility

Different SBR grades can be selected for common processes such as mixing, extrusion, calendaring and molding.

Cost Efficiency

Compared with many specialty elastomers, SBR provides balanced general-purpose performance at a competitive material cost.

Compound Compatibility

SBR can be blended with natural rubber, polybutadiene rubber and common compounding ingredients to adjust processing behavior and finished-product properties.

Applications

Tires and Automotive Rubber

SBR is widely used in tire compounds and selected automotive rubber parts where abrasion resistance, flexibility and durability are required.

Footwear and Soles

Commonly used in shoe soles and molded footwear components for wear resistance, elasticity and processing efficiency.

Hoses and Conveyor Belts

Suitable for industrial hoses, conveyor belts and other rubber products exposed to repeated movement and friction.

Molded and General Rubber Products

Used in rubber sheets, mats, gaskets, molded parts and other general-purpose rubber applications.

Adhesives and Rubber Modification

Selected grades can also be used in adhesive systems and rubber modification where flexibility and bonding performance are required.

FAQ

1. How do I choose an SBR grade?

Grade selection usually depends on Mooney viscosity, oil extension, processing method and the final application. Polykem can support grade matching based on customer specifications or reference materials.

2. What is the difference between oil-extended and non-oil-extended SBR?

Oil-extended SBR contains processing oil, which can improve softness and processing behavior. Non-oil-extended grades give customers more flexibility to adjust the compound formulation.

3. Is SBR suitable for oil-resistant applications?

SBR has limited resistance to oils and fuels. For applications involving frequent contact with petroleum-based fluids, NBR or other oil-resistant rubber materials may be more suitable.

4. Can Polykem provide free samples and product documents?

Yes. Free samples are available for qualified projects. COA, SDS, TDS and other available quality documents can also be provided according to product and customer requirements.
