Characteristics: This product is made by solution polymerization under which styrene and butadiene react in organic solvent using alkyl-lithium catalyst. It is superior to SBR, which is made by emulsion polymerization, in processability, visco-elasticity and low temperature properties. Also, the products' properties can be adjusted to the purpose of consumption according to the proper proportion of styrene content, the micro structure and the molecular weight.

Applications: Shoes, Soles, Tires, Machine Parts, Energy-saving Tires, High-efficiency Tires
