Styrene butadiene rubber is produced in the low-temperature emulsion copolymerisation process and is coagulated with the acid-synthetic coagulant system. Some types of styrene butadiene rubber contain aromatic oils. Staining or non-staining antioxidants are used for stabilisation of styrene rubber. The styrene butadiene rubber is used for the production of tires, tire tubes, conveyor belts, shoe soles, cables, hoses and other technical rubber products. The non-staining rubber types are used for floor coverings in light colours, bicycle tires and tubes, shoes, toys, cables, hoses and other rubber products in light, pastel colours. The styrene butadiene rubber produced by SYNTHOS is sold under the trade name KER® and KRALEX®.
The production process of the new solution styrene-butadiene rubber is based on anionic co-polymerization of butadiene and styrene in a hydrocarbon solvent, in the presence of a lithium catalyst.
We manufacture rubbers with varying Mooney viscosity, bound styrene and vinyl structure content, oil-extended and dry.
For the production of oiled types of SSBR, we use plasticising oils with low polycyclic aromatic hydrocarbon content of TDAE types or heavy naphthenic oil. Dry types can be used also for the production of various technical rubber products. This technology also allows us to manufacture butadiene rubber with low cis-structure content and SSBR with semi-block structure, mainly for purposes other than tire production. All rubber is stabilized with a non-staining anti-oxidant. Thanks to the optimized structure of the SYNTION® rubbers and their low polydispersion, it is possible to manufacture tires with low rolling resistance and an increased grip on wet surfaces.
