Methyl dichloride, also known as Methylene chloride, dichloromethane, or DCM, is a volatile, colorless liquid with a sweet, chloroform-like odor. Methyl dichloride is widely used as a solvent in various industries such as paint and varnish removers, aerosols, foams, cosmetics, pharmaceuticals, and adhesives.
When rubber is exposed to methyl dichloride it can cause swelling, cracking, softening, and embrittlement of the rubber. Low molecular weights can cause premature hardening, oxidation, and loss of elasticity. Long-term exposure to methyl dichloride can cause gradual deterioration of the rubber and may accelerate aging.
