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 color or light colored rubber products, such as soles, rubberized fabric, medical supplies, rubber rolls, tires and the rubber products which has an environ?mental requirement to raw rubber materials.
