Product Description

Overview:
The product is produced using the low-temperature emulsion polymerization method with butadiene and styrene as monomers and the complex soap of potassium dispro?portionated rosinate or potassium rosinate soap with fatty acid soap as the emulsifier. It is free from nitrosamines and salt.

APPLICATIONS:
Environment friendly styrene-butadiene rubber (SBR), which has a wide application in producing the color-undemanding products with black carbon as the reinforcing agent, such as tire treads, conveying belts, hoses, black shoe soles and the rubber products that has an environmental requirement to raw rubber materials.
