Styrene Butadiene Rubber (SBR) 1712 is a type of synthetic rubber that is a copolymer of styrene and butadiene. It is commonly known as SBR and is widely used in various industrial applications. SBR is produced by the polymerization of styrene and butadiene monomers, resulting in a material with properties that combine the characteristics of both components.
SBR 1712 has the following key properties:
Good abrasion resistance: SBR is known for its excellent resistance to abrasion, making it suitable for applications where wear and tear are common, such as in tires and conveyor belts.
High resilience: SBR exhibits high resilience, allowing it to recover its original shape after being subjected to deformation or stress. This property is valuable in products like shoe soles and other elastomeric components.
Weather resistance: SBR can withstand exposure to various weather conditions without significant degradation, making it suitable for outdoor applications.
Good adhesion: SBR has good adhesion properties, which make it useful in applications where strong bonding is required, such as in adhesive formulations and coatings.
Versatility: SBR can be easily blended with other rubbers and additives to achieve specific performance characteristics, making it versatile for a wide range of applications
Tire Manufacturing: SBR 1712 is widely used in the production of vehicle tires, including passenger car tires, truck tires, and motorcycle tires. It is used as a component in tire tread compounds to improve wear resistance and traction.
2. Footwear Industry: SBR 1712 is commonly used in the manufacturing of shoe soles and outsoles due to its high resilience and excellent abrasion resistance, making it suitable for both casual and athletic footwear.
3. Conveyor Belts: SBR 1712 is used in the production of conveyor belts for various industries, such as mining, agriculture, and material handling, to enhance the belts' durability and resistance to wear and tear.
4. Gaskets and Seals: SBR 1712 is utilized in the production of gaskets and seals for applications where good sealing properties and resilience are essential, such as in automotive engines, pipes, and hydraulic systems.
5. Adhesives and Coatings: SBR 1712 is used as a binder in adhesive formulations and coatings due to its good adhesion properties, which improve bonding and durability.
6. Vibration Dampening: SBR 1712 is employed in manufacturing vibration isolation mounts and damping components to reduce vibrations and noise in various industrial equipment.
7. Industrial Belts: SBR 1712 is used in the production of industrial belts, such as power transmission belts and V-belts, to provide durability and resistance to wear.
8. Mechanical Rubber Goods: SBR 1712 is used to produce various mechanical rubber goods, including rubber hoses, seals, O-rings, and other molded rubber products.
9. Sports Equipment: SBR 1712 can be found in sports equipment like yoga mats, exercise mats, and padding due to its resilience and impact resistance.
10. Electrical Insulation: SBR 1712 is used as an insulating material in electrical applications due to its electrical resistance and flexibility
