Product Application of Tetrachloroethylene CAS#127-18-4
Tetrachloroethylene (PCE) is also known as perchloroethylene, tetrachloroethene, and 1,1,2,2- tetrachloroethene and is also commonly abbreviated to PER or PERC. Tetrachloroethylene is a volatile, chlorinated organic hydrocarbon that is widely used as a solvent in the dry-cleaning and textile-processing industries and as an agent for degreasing metal parts. It is an environmental contaminant that has been detected in the air, groundwater, surface waters, and soil (NRC, 2010).
