Butadiene Rubber NEW

Chemical Name:

Butadiene-styrene copolymer

CAS No: 

9003-55-8

Styrene-Butadiene Rubber (SBR) is the most widely produced synthetic rubber globally. As a copolymer of styrene and butadiene, it is renowned for its excellent abrasion resistance, aging stability, and cost-effectiveness. Its versatility makes it a fundamental material in numerous industries.

Here are its key applications:

1. Tire Manufacturing

SBR is the primary material for car and truck tires, especially for treads and sidewalls. Its outstanding abrasion resistance significantly extends tire life. The "cold rubber" process, which accounts for most SBR production, is optimized for tire performance.

2.  Automotive Parts

Beyond tires, SBR is used in various automotive components such as belts, hoses, gaskets, and seals. Its good mechanical properties and resilience make it suitable for these under-the-hood and chassis applications.

3. Industrial & Consumer Products

SBR is a key material in conveyor belts, transmission belts, and industrial hoses due to its durability. It is also widely used in shoe soles and heels for its slip resistance and wearability.

4. Foam Products & Adhesives

SBR latex (a water-based dispersion) is extensively used to produce flexible foam for mattresses, furniture cushioning, and carpet backing. It also serves as a crucial base for many pressure-sensitive adhesives, sealants, and paper coatings.
