Chemical Designation: Styrene Butadiene, Buna S, GRS

Molded SBR rubber is an economical substitution for Natural Rubber in many applications because it provides significant cost savings. SBR is a good choice for applications where finished product exposure includes acids, organic salts and alkalis. In addition, SBR Rubber is soft and has good flexing characteristics at low temperatures, like Natural Rubber. It is wear resistant and non-toxic. 

Do not use SBR Rubber for applications that involve petroleum derivatives or exposure to chemicals. Special formulations of SBR can provide sunlight and heat resistance.

Red SBR Rubber is popular for use as a gasket in low-pressure applications, such as washers and gaskets for heating and plumbing.  Black SBR is popular for use in applications where abrasion is a factor.
