2H,3H-Decafluoropentane

2,3-Dihydrodecafluoropentane is a unique HFC liquid (HFC-4310) with zero ODP value and low GWP value, commonly used for cleaning, rinsing, and drying in steam degreasing equipment. It can replace existing HCFCs and PFC liquids in most applications. It has a higher boiling point and lower surface tension than CFC 113, and a stronger solubility than CFC 113. However, it can also be blended with alco

2,3-Dihydrodecafluoropentane is a colorless transparent liquid with minimal non-volatile residues, making it ideal for applications requiring extremely high cleanliness. It is an HFC liquid (HFC-4310) with zero ODP and a very low GWP, commonly used for cleaning, rinsing and drying in vapor degreasing equipment. It can replace existing HCFC and PFC liquids in most applications. It has a higher boiling point and lower surface tension than CFC-113, and also features non-flammability, chemical stability, thermal stability and low toxicity, as well as easy regeneration via distillation. This product has stronger solvency than CFC-113; it can also be mixed with alcohols, hydrocarbons, esters, etc. to form azeotropes or blends for enhanced solvency.
