SBR stands for styrene-butadiene rubber and is a widely used product used in a number of industrial, automotive and commercial applications as a cost effective replacement for natural rubber.  Common uses of SBR rubber include rubber pads, o-rings, hydraulic brake systems seals and diaphragms, grommets, gaskets, conveyor belts, isolation pads, shelf liners, workstation table liners, dishwasher drain hoses, HVAC ductwork isolation connectors, work area liners and a wide variety of industrial and production line applications. 

The main limitation to the product is its use in any application where the product is exposed to high pressure, ozone, strong acids, oils, grease and most hydrocarbons, although use in moderate chemical and hydrocarbon environments is acceptable.  

Beyond the lower cost, there are a number of benefits to SBR as a replacement to natural rubber.  One of the biggest benefits is the product’s ability to perform as designed in temperatures from -30° to over 210° without failure.  In addition, the product is versatile, flexible and strong, while also possessing above average abrasion and tensile strength characteristics. 

It also features above average water resistance qualities, with resilience up to 70 durometers, which is a means to measure the hardness of the SBR.  Another feature of SBR rubber is that it is manufactured without the use of chloroprene, which is considered to be a “Hazardous Class 3 Flammable Liquid”, with significant restrictions on its transfer..  SBR rubber is available in roll lengths that are cut to order and is available in a variety of thicknesses.
