Industrial Rubber Products and Tyres- Carbon black is applied for uses like innerliners for tyres, sidewalls and treads, for industrial rubber products, usages include belts, hoses and gaskets. In fact a majority of the Carbon Black that is produced goes into the making of reinforcing filler for use in tyres and other rubber article.
