ASTM D-1418 Designation: SBR
Chemical Definition: Styrene-butadiene
Abbreviation: SBR, Buna-S
Styrene-Butadiene or Styrene-Butadiene-Rubber (SBR) is a synthetic rubber copolymer consisting of styrene and butadiene. It has good abrasion resistance, water resistance, moderate resistance, chemicals resistance, organic acids resistance, alcohols resistance, ketones resistance and aldehydes resistance, and good aging stability when protected by additives.
Styrene-Butadiene-Rubber, however, has its disadvantages, that it could be attacked by ozone, sunlight, strong acids, fats, oils, open flame, grease and most hydrocarbons.

SBR is used widely in pneumatic tires, shoe heels and soles, gaskets and even chewing gum. It is a commodity material which competes with natural rubber. SBR is also used in building applications, as a sealing and binding agent behind renders as an alternative to PVA, but is more expensive. In the latter application, it offers better durability, reduced shrinkage and increased flexibility, as well as being resistant to emulsification in damp conditions. SBR can be used to 'tank' damp rooms or surfaces, a process in which the rubber is painted onto the entire surface (sometimes both the walls, floor and ceiling) forming a continuous, seamless damp proof liner; a typical example would be a basement. Additionally, it is used in some rubber cutting boards.
