Benzophenone and benzoquinone are both chemical compounds with the molecular formula C6H5CO. Benzophenone is used as a dye and a preservative in food and cosmetics, as well as an intermediate in the pharmaceutical industry. Benzoquinone is used in the production of dyes, pigments, and specialty coatings.
Common types of rubber failures when exposed to benzophenone and benzoquinone include cracking, swelling, softening, embrittlement and loss of strength. These chemicals can also cause rubber to degrade, leading to a decrease in elasticity and an increase in brittleness. In some cases, the rubber may become discolored or stained. Finally, it is possible for these chemicals to cause corrosion or even degradation of the rubber material.
