what is sbr
Styrene-butadiene rubber (SBR) is one of the most versatile copolymer rubber compounds. It consists of the organic compound styrene and the chemical budatiene, with the amount of budatiene usually being about three times more than the amount of styrene. SBR is a stable synthetic that is resistant to abrasion. It is used in a wide variety of products, such as automobile tires, children's toys, shoe soles and even chewing gum. This compound is produced either through ionic polymerization of a solution or as an emulsion through free radical polymerization.
