SBR 1502

Product Description

Styrene-butadiene rubber (SBR) is the most widely used general-purpose rubber among all synthetic rubbers. SBR is the major raw material in the manufacture of automobile tires, shoe soles, conveyor belts, rubber tubing, tank and caterpillar tracks, sporting goods, toys and many others. From this array of products, it is obvious SBR plays an important role in our daily lives. Unlike natural rubber, which is limited by climate and geographical locations, SBR has staked out a firm claim on part of the natural rubber market, and its application is continually being explored. Characteristics: Bright colored stock with excellent color stability. Improved abrasion resistance, flexibility. Application: Tires whitewalls and carcasses, a range of mechanical goods such as white or light colored sporting goods, floor coverings, shoe soles and heels and refrigerator gaskets. Specification: To meet the different customer's requirement, SBR1502 include two specifications: GB spec. (That is suitable for the Chinese user)and Normal spec. (That is suitable for many users in other countries).

  SBR 1712

SBR1712 , The aromatic oil used is an efficient plasticizer for high molecular

weight SBR and results in superior physical and processing properties compared to other oil-extended rubbers.

It is used on tires , belts, and other goods compounds where color and staining are not decisive factors.
