SYNTHETIC RUBBER Synthetic Rubber Styrene-Butadiene rubber (SBR) Government rubber styrene (GR-S) Buna-S What is “Synthetic Rubber”? A synthetic rubber is a material which can : Undergo much more elastic deformation under stress than most materials. Return to its previous size without permanent deformation. STYRENE - BUTADIENE RUBBER Styrene - Butadiene Rubber : o Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of styrene rubber derived from styrene and butadiene. o Styrene – butadiene rubber (SBR) is made by using 75% butadiene and 25% styrene by weight . It is a block co-polymer. [...]...USES Uses : • SBR is the most widely used rubber • It is used in making tyre of vehicles/motors • Other uses are , floor tiles , shoe soles , gaskets , footware components , wire and cable insulation , carpet backing, conveyer belts , etc NATURAL RUBBER V/S SYNTHETIC RUBBER NATURAL RUBBER V/S SYNTHETIC RUBBER NATURAL RUBBER VULCANISED RUBBER SYNTHETIC RUBBER Low tensile strenght – 20kg/cm2 Higher .
