Styrene Butadiene Rubber Latex

Styrene butadiene sb latex is a common type of emulsion polymer used in a number of industrial and commercial applications.

Styrene butadiene rubber latex.

Styrene is derived from reacting benzene and ethylene and butadiene is a byproduct of ethylene production. These materials have good abrasion resistance and good aging stability when protected by additives. Because it s composed of two different types of monomers styrene and butadiene sb latex is classified as a copolymer. The remaining consumption is for sbr latexes which are used mostly for molded foams and adhesives.

In industry sb latexes are most widely used for coated pigmented paper and paperboard coatings and carpet backcoatings and accounted for a vast majority of worldwide styrene butadiene latex consumption in 2016. Exceeding all other synthetic rubbers in consumption sbr is used in great quantities in automobile and truck tires generally as an abrasion resistant replacement for natural rubber produced from polyisoprene. The styrene butadiene ratio influences the properties of the polymer. About 50 of car tires are made from various types of sbr.

The toughness was significantly improved 12. The use of styrene butadiene rubber sbr emulsions in concrete has been increasing in concrete construction and repair work due to its benefits to flexure strength adhesion and impermeability. With high styrene content the rubbers are harder and less rubbery. While the macro mechanical properties of differ ent polymer latex modified cementitious materials are reported in the literature little is known on the impact of polymer latexes on the micro mechanical properties of cement paste and its effect.

Sbr latex anionic is a soft anionic sbr with a cross linking agent designed for use in asphalt and asphalt water proofing modifications. Styrene butadiene or styrene butadiene rubber describe families of synthetic rubbers derived from styrene and butadiene. Styrene butadiene rubber sbr a general purpose synthetic rubber produced from a copolymer of styrene and butadiene. Sbr latex is a carboxylated styrene butadiene copolymer latex admixture that is designed as an integral adhesive for cement bond coats mortars and concrete to improve bond strength and chemical resistance.

The product has excellent water resistance tensile and elongation properties and has excellent adhesion to a variety of substrates. Allowance of styrene butadiene rubber sbr latex. In 2012 more than 5 4 million tonnes of sbr were processed worldwide.
