Styrene Butadiene (SBR)

Styrene Butadiene Rubber (SBR) is a cost-effective, general-purpose elastomer offering good abrasion resistance, aging stability, and versatile performance. Mountville Rubber mixes SBR compounds that are a dependable choice for a wide range of products, from conveyor covers and flooring systems to gaskets and seals. SBR is often selected for industrial applications where value and durability must go hand in hand.

Available in sheets, slabs, and strips.
