Tetrachloroethylene (Perchloroethylene, PCE)<\/p>\n

Tetrachloroethylene, commonly abbreviated as\u00a0PCE\u00a0(IUPAC name:\u00a0tetrachloroethene, CAS No. 127-18-4), is a colorless, non-flammable organochlorine liquid with a faint, sweet ether-like odor. It is a high-performance industrial solvent widely used in dry cleaning and metal processing, with well-defined safety and regulatory requirements due to its environmental persistence.<\/p>\n

Main Industrial Uses<\/h3>\n

Dry Cleaning Agent<\/h6>\n

It is the most widely used solvent in the dry cleaning industry due to its strong ability to dissolve oils, greases, and stains, and its low flammability reduces safety risks during use.<\/p>\n

Metal Degreasing Agent<\/h6>\n

In manufacturing processes (such as aerospace, automotive, and electronics), it is used to remove grease, oil, and other contaminants from metal surfaces to ensure product quality and performance.<\/p>\n

Chemical Intermediate<\/h6>\n

It serves as a raw material for the production of other chemicals, including fluorinated compounds, plastics, and synthetic rubber.<\/p>\n

Textile and Leather Processing<\/h6>\n

It is applied in textile scouring and leather degreasing to improve the cleanliness and finish of products.<\/p>","protected":false},"excerpt":{"rendered":"
