Product Description

Overview:
The product is produced using the low-temperature emulsion polymerization method 
with butadiene and styrene as the monomers and the potassium rosinate soap and 
fatty acid soap as the emulsifiers. It is filled with high aromatic oil.

APPLICATIONS:
Oil-filled styrene-butadiene rubber (SBR), which is used in producing tyre tread rub?ber, conveying belts, hoses and other general purpose black rubber products.
