Breakthrough In Key Technologies Of Soluble Polystyrene-butadiene Rubber In China

Soluble styrene-butadiene rubber SSBR1040 has good low temperature resistance. It is the best material for preparing snow tires, and it is also a badly needed but not yet industrialized brand in China. The joint research team solved a series of technical problems by optimizing the feeding mode of coupling agent. After 38 batches of pilot tests, the Mooney viscosity, coupling efficiency and microstructure of the product are stable, and the device runs smoothly, which marks the success of the brand certification of snow tire products.
