Blowing agents generates gas expands rubber gives elasticity, heat insulation, permeability


Carbon Tetrabromide

Carbon tetrabromide is a carbon bromide. It is used as a solvent for greases, waxes and oils, in plastic and rubber industry for blowing and vulcanization, further for polymerization, as a sedative and as an intermediate in manufacturing agrochemicals. Due to its non-flammability it is used as an ingredient in fire resistant chemicals. It is also used for separating minerals because of its high density.
