PERC stands for perchloroethylene, which is a chemical compound commonly used as a solvent in various industries. It is a colorless liquid with a sweet, ether-like odor and is primarily utilized in dry cleaning, metal degreasing, and as a component of some consumer products.
In the dry cleaning industry, PERC is highly valued for its exceptional cleaning properties and ability to dissolve tough stains. It effectively removes dirt, grease, and oils from fabrics without causing damage or shrinking. Additionally, its low flammability and high boiling point make it a safe choice for the dry cleaning process.
In metal degreasing applications, PERC is an efficient solvent used to clean machinery, tools, and parts. It has excellent degreasing capabilities, effectively removing oils, lubricants, and other contaminants from metal surfaces. The high solvency power of PERC also makes it suitable for removing grease and carbon residue from automotive parts and electrical components.
However, it is important to note that PERC has been found to be a potential environmental and health concern. Long-term exposure to PERC has been associated with various adverse health effects, including respiratory irritation, central nervous system disorders, and potential carcinogenicity. Due to these concerns, many countries and jurisdictions have implemented regulations to reduce or phase out its use.
Overall, PERC is a powerful solvent with diverse industrial applications, particularly in dry cleaning and metal degreasing. However, its potential health and environmental implications call for caution and alternative methods wherever possible.
