Styrene-butadiene rubber (SBR) are synthetic rubbers derived from styrene and butadiene. These materials have good abrasion resistance and good aging stability when protected by additives. The styrene/butadiene ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery.

Key Features(Emulsion SBR (e-SBR))

1.Green strength becomes low with increasing oil extension

2.Low resilience and low tensile strength

3.Outstanding resistance to abrasion

4.Low resistance to oil, other hydrocarbon fluids, and ozone

5.Hot polymers are difficult to process with low green strength

6.Poor tear strength

7.High styrene resins have good low-temperature properties but stiffen.

(Key Features)Solution SBR (s-SBR)

1.Improved flexibility and performance

2.Good resilience, tensile strength, and low rolling resistance when used in tires

3.Outstanding resistance to abrasion and fatigue

4.Low resistance to oil, other hydrocarbon fluids, and ozone

Main applications of styrene butadiene rubber include tires and tire products, automotive parts, and mechanical rubber goods.
