Styrene butadiene rubber (SBR), also known as polystyrene butadiene copolymer.
Emulsion polystyrene butadiene rubber, with butadiene and styrene as the main monomers, and other auxiliary chemical raw materials, under certain process conditions, the emulsion polymerization first generates styrene-butadiene rubber paste, and removes unconverted rubber in the rubber paste. After the monomer, the product gum is produced through the processes of coagulation and drying.
Solvent-polymerized styrene-butadiene rubber, which uses butadiene and styrene as the main monomers, and uses a lithium compound as an initiator in a hydrocarbon solvent to initiate anionic polymerization. A polymer glue prepared by adding an antioxidant and other additives After that, the product gum is produced through the processes of coagulation and drying.
SBR’s physical mechanism performance, processing performance and product performance are close to natural rubber. Some properties such as abrasion resistance, heat resistance, aging resistance and vulcanization speed are better than natural rubber. It can be used with natural rubber and various synthetic rubbers.
SBR is widely used in the production of tires, tapes, hoses, wires and cables, medical equipment, and various rubber products. It is the largest variety of general synthetic rubber and one of the earliest types of rubber to achieve industrial production.
