Description
Perchloroethylene (CAS 127-18-4), also known as PCE, PERC, PerSec, and Nema, is a nonflammable chlorinated solvent with the molecular formula C2Cl4. It carries no assigned E-code and is classified under HS code 29032300. It is commercially available as a high-purity industrial solvent within the Solvents category.
In textile and leather processing, PCE dissolves fats, oils, and waxes from fiber substrates without damaging the material, enabling effective dry cleaning and degreasing. In plastics and polymer manufacturing, it functions as a carrier solvent and monomer processing aid, facilitating controlled dispersion of colorants and reactive intermediates during compounding operations.
Perchloroethylene is supplied in technical and high-purity grades compliant with REACH registration requirements applicable in the EU. Standard packaging includes drums and IBC containers, with bulk delivery available depending on volume. Procurement should verify current REACH substance restrictions and occupational exposure limit obligations prior to ordering.
