Dichlorofluoroethane(HCFC-141b) is a non-toxic and colorless transparent liquid under normal temperature. It has low ODP value and excellent chemical stability. Since its physical and chemical properties are similar to those of CFC-11 and CFC-113,it can substitute CFC-11 as the foaming agent for hard and flexible polyurethane foam, or it can be a substitute for CFC-113 as metal cleaner and deflux. It is a worldwide acknowledged substitute for CFCs.
The HCFC-141b has the following characteristics:
1. Chemical Stability:It can be stored at room temperature without decomposition.
2. Corrosion: Even being boiled,it does not corrode iron and steel, stainless steel, copper, brass, aluminum, zinc, etc.
3. Solubility: It is soluble in most organic solvents, alcohol and ether. It has excellent compatibility with grease and lubricating oil, and no obvious effects on most macromolecular compounds including plastics and rubbers.
4. Toxicity: The toxicological testings conducted by the International PAFT II Association indicate that the HCFC-141b has no irritant effect on human skin and eyes, but inhalation of high-concentrated HCFC-141b will cause anaesthetic effect.
HCFC141b is a kind of high purity of liquid, widely used in cleaning and solvent field

Dissolve force: high KB value, selective solubility.
Reliability: to all sorts of materials has high adaptability and can be used for all purposes.
Speed dry: the fine dry, do not appear to spots, etc, and maintain a good processing quality.
Energy conservation: low boiling point, low QiHuaRe.
Safety: no flash point, belong to the combustible liquid. Equipment set up more easily.
Regenerative: through the equipment within the distillation regeneration dropped sharply industrial wastes.
environmental: ODP for CFC113 10 , GWP of 12.6 for CFC113.
Permeability: low surface tension, and mobile
