SBR- 1500 is the most typical pollution-free soft emulsion polystyrene rubber. Its raw rubber has excellent adhesiveness and processability, and its vulcanized rubber has good wear resistance, tensile strength, tear strength and aging resistance. SBR- 1500 is widely used in products with carbon black as reinforcing agent and low color requirements, such as tire tread, tread compound, conveyor belt, rubber hose, molded products and extruded products.
SBR- 1502 is the most typical pollution-free soft emulsion polystyrene rubber. Its performance is equivalent to SBR- 1500, and it has good tensile strength, wear resistance and flexibility. SBR- 1502 is widely used in brightly colored and light colored rubber products, such as tire sidewalls, transparent rubber shoes, adhesive tapes, medical supplies and other general colored products.
SBR- 17 12 is a kind of pollution-free soft emulsion SBR filled with high aromatic oil, which has the advantages of excellent adhesion, wear resistance, processability and low price. SBR- 17 12 is widely used in passenger car tire tread compound, tire tread compound, conveyor belt, hose and general black rubber products.
The production technology of emulsion polymerized styrene-butadiene rubber gradually matured in the late 1920s of 19. Since then, the process has been continuously improved, and it has developed towards the direction of large-scale equipment. The level of automatic control has been obviously improved, reaching a quite advanced level.
At present, emulsion polymerized styrene-butadiene rubber has made great progress in improving monomer conversion rate, saving energy and reducing consumption, and has also made breakthrough progress in solving the contradiction between rolling resistance and wet skid resistance of emulsion polymerized styrene-butadiene rubber, optimizing product performance and adapting to market demand.
The properties of emulsion polymerized styrene-butadiene rubber were optimized by developing a new functional initiator, a new efficient environmental protection additive, introducing a third monomer and increasing the content of bound styrene. The development of environmentally friendly emulsion polymerized styrene-butadiene rubber has also made remarkable progress by using environmentally friendly additives and environmentally friendly filling oil.
