refrigerant gas R134a

R134a is new-type, environmental protection. High-efficient and energy-saving refrigerant. Innocuous, colorless and nonflammable. Has good hot stability and the chemical property is steady. Compared with F12, its ODP is zero and GWP is 0.27 and the refrigeration ability is equal. At present, R134a is regarded as the best substitute of R12 and works with polyol-ester (POE68) oils well Main use: Applied to the air conditioner of the automobile and refrigeration system of the central air conditioner extensively. It can be used in medicine and cosmetics aerosol etc, too.
