Application:
SBR resilience and good abrasion resistance, heat is low, the permanent tensile deformation is small,
Dynamic performance and low temperature flexion bending performance is excellent, the oil filled low
Along the rubber product colorless, transparent, high purity, does not contain the transition metal,
Soluble in benzene,hexane, gasoline and other solvents, especially soluble in styrene and
Solution viscosity is low, suitable for polystyrene, ABS plastic modification, etc. SBR can be widely
Used in th rubber, tyre plastic hosoe tapes, conveyors, rubber tubes, black sole, rubber lines, and so on.
