Cymene is another name for p-cymene and is a monoterpene hydrocarbon. It is most commonly used as a solvent in the paint and coatings industry, as an intermediate in organic synthesis, and as a flavoring agent in food products.
When rubber is exposed to cymene, it can cause swelling, softening, and reduced elasticity. The rubber can become brittle and prone to cracking, and the surface may become sticky or tacky due to the breakdown of the polymer chains. Additionally, exposure to cymene can cause discoloration and a decrease in the strength of the rubber. In extreme cases, the rubber can become completely degraded and unable to provide the necessary seal.
