SBR 1778E (Emulsion Type Styrene Butadiene Rubber)

Date：2023-09-20 09:50:50VIew：

Overview:
This product is produced using the low temperature emulsion polymerization method with butadiene and styrene as the monomers, the mixed soap as the emulsifier, filled with the naphthenic base oil and a non-color type antioxidant as the additive. It is free from nitrosamines and salt.

APPLICATIONS:
Environment friendly oil-filled SBR, which is mainly used for producing advanced tire tread rubber.
