Acetone on Rubber: Chemistry and Technical Overview
Acetone (C3H6O) acts as a powerful solvent in the rubber industry, ensuring efficient dissolution of rubbers (such as acrylonitrile butadiene rubber NBR) and enhancing surface cleaning before vulcanization or bonding. These processes are vital in manufacturing tires, industrial hoses, and gaskets, as well as in adhesive preparation.
