Tetrachloroethylene (PCE)

Also known as: Perchloroethylene, Perc, PCE, PerSec, Tetranec
Chemical reference number (CAS): 127-18- 4

Tetrachloroethylene (PCE) is a nonflammable, liquid solvent widely used in dry cleaning, wood processing, fabric manufacturing, and metal degreasing. In homes, it may be found in suede protectors, paint removers, furniture stripper, water repellents, silicone lubricants, spot removers, glues, and wood cleaners. PCE evaporates slowly at room temperature and has a sweet, ether-like odor.

When PCE is improperly disposed of or spilled, most of it will evaporate into the air. The rest will seep into the soil. It may mix with groundwater and contaminate water supplies.
