Tetrachloroethylene: Overview

Description

The largest user of tetrachloroethylene is the dry cleaning industry. It is a large percentage of all dry cleaning fluid used. Textile mills, vapour degreasers and metal cleaning operations, and rubber coatings also use tetrachloroethylene. It can be added to solvent soaps, printing inks, adhesives, sealants, polishes, lubricants and silicones.

Substance details

Substance name: Tetrachloroethylene

CASR number: 127-18-4

Molecular formula: C2Cl4

Synonyms: Perchloroethylene; PERK; PERC; Ethylene tetrachloride; tetrachloroethene; 1,1,2,2-tetrachloroethylene; carbon dichloride; perchlor; tetrachloroethane; carbon bichloride; perk
