Chloroform, also known as trichloromethane, is a colorless, sweet-smelling and nonflammable liquid with a variety of commercial, industrial and medical applications. It is often used as a solvent for waxes, fats, oils, rubber and resins. It is also used as a component of anesthetic solutions and as a laboratory reagent.
When rubber is exposed to chloroform, it can cause softening, swelling and cracking of the rubber. Chloroform can also cause weakening of the rubber, making it more susceptible to tearing and cracking. It can also cause discoloration of the rubber and can be corrosive to metal components of the rubber seal.
