Tyre industry is facing another blow with increasing price of synthetic rubber which is following the price increase of crude oil. The country is already facing shortage of carbon black which is a key raw material. Currently, India imports more than half its requirement of synthetic rubber, which is a derivative of crude oil. While imported SR varieties have increased 20-25%, industry players said that local manufacturers were poised to raise prices. Then rubber industry uses styrene butadiene (SBR) and poly butadiene. Unlike in the case of bus and truck radial tyres, the percentage of synthetic rubber used is higher in passenger car radials for speed and performance.
