1)Perchloroethylene is the predominant solvent used in the dry cleaning industry because it is non-flammable, stable but highly volatile.It is safe to use on most textiles,fibres and dyes without causing damage to the garment.
2) It is highly effective at removing oils, greases and fats from textiles due its high boiling point and volatile nature.A wide array of industries use perchloroethylene because it is excellent at degreasing metal parts during the production of products.
3)used in extracting fats, dissolving rubber, paint removal, water repellent, brake cleaning and a carrier solvent.
4)historically used as a chemical intermediate in the manufacture of hydrofluorocarbon (HFC) 134a.
