In this method, polymerization is done through free radicals, which is done in both hot and cold states. The product obtained by cold method in the presence of oil or in the presence of oil-soot has high linearity, narrow molecular distribution, high molecular weight and difficult processing. (Series 1500 (Type 1500)). The product obtained by hot method is also highly […]
Styrene butadiene rubber emulsion method In this method for styrene butadiene rubber , polymerization is done through free radicals, which is done in both hot and cold states. Styrene butadiene rubber obtained by cold method in the presence of oil or in the presence of oil-soot has high linearity, narrow molecular distribution, high molecular mass and difficult processing. Styrene butadiene […]
Synthetic rubber Styrene butadiene rubber While most of the properties of SBR are comparable with NR, but in some respects like heat build-up, tack and gum tensile strength make it inferior to natural rubber. Other disadvantages include: Low elongation at break Low hot tear strength Hysteresis, resilience . But the addition of resins and reinforcing fillers adequately improve these properties. […]
