Perchloroethylene

Perchlorethylene or perchlor is a chlorinated solvent produced by PPG Industries and used extensively by dry cleaning plants. Other applications include vapor degreasing, and use as a chemical intermediate and processing solvent. Perchlor is nonflammable, has low toxicity, and has an inherent stability further enhanced by PPG’s stabilizer system.

Properties and Characteristics
Perchlor has no flash point and no fire point, which gives it an important advantage over petroleum distillates such as Stoddard solvent for dry cleaning operations. As a result, along with its desirable physical properties, Perchlor has become the largest-volume dry cleaning solvent. Perchlor is relatively inert, and is inherently more stable than other chlorinated solvents. PPG’s perchlor is further stabilized to prevent solvent degradation...

General Applications
In addition to its wide use as a drycleaning solvent, PPG’s perchlor is used extensively for vapor degreasing because of its high solvency, non-flammability and high vapor density. Drycleaning—Perchlor is the preferred solvent because, in addition to its non-flammability, it provides a fast, powerful yet gentle cleaning...
