Good Abrasion Resistance • Excellent Impact Strength • Superior Resilience • High Tensile Strength

SBR Rubber Products

SBR is a copolymer of styrene and butadiene and has properties similar to Natural Rubber. It has good abrasion resistance, excellent impact strength, very good resilience and a high tensile strength. The temperature range of SBR is -40˚F to +180˚F. SBR can be compounded for use as lining rubber, conveyor belt covers and other extremely demanding applications.
