Tetrachloroethylene (PCE) and Trichloroethylene (TCE) are chlorinated liquid hydrocarbons, primarily used as degreaser agents for the cold cleaning of fabricated metal parts. They serve as general solvents for resins, fats, oils, waxes, rubber, paints, cellulose esters and ethers, and varnishes.
What is Tetrachloroethylene?
Tetrachloroethylene, also known as perchloroethylene (PCE or PERC), is a nonflammable colorless liquid used for dry cleaning operations and as a starting material to synthesize other compounds.
What is Trichloroethylene?
Trichloroethylene (TCE) is a volatile organic solvent used in multiple manufacturing industries (e.g., aircraft, spacecraft, electronic) to remove grease from metal parts.
They are all colorless chemicals. TCE is a solvent used for cleaning metal parts. PCE is used for dry cleaning and metal degreasing. TCE and PCE degrade in groundwater over time to VC.
