Product Overview
Perchloroethylene is a high-density chlorinated solvent widely used in industrial degreasing, dry-cleaning, chemical processing and specialised solvent applications.
It provides strong solvency for oils, greases and many organic soils while being non-readily-flammable under ordinary conditions.
