SBR Parts

Minor Rubber manufactures SBR rubber parts.  SBR (styrene-butadiene rubber) is a low cost non-pil resistant material. It has good water resistance and resilience up to 70 durometer; compression set becomes poorer with higher durometer; generally satisfactory for most moderate chemicals and wet or dry organic acids. SBR is not recommended for ozone, strong acids, oils, greases, fats and most hydrocarbons. SBR can be molded
