Product characteristics:
SBR1712 general properties is stable, Storage period is longer, property is
similar with the natural rubber. Under the reaction in Light、Hot、Oxygen and Ozone ,Happen physical and chemical reaction, Oxidation slow. The cold resistance of the SBR1712 is poor performance than the natural rubber, reboundelasticity is bad. But the wear resisting property、heat-resistant quality、oil resistant and ageing-resistant performance are bette than natural rubber.
