Dichlorofluoroethane (HCFC-141b) is a nontoxic and colorless chemical with small 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 foaming agent for rigid or soft PU foam without changing process and equipment, or CFC-113 as metal cleaner and solder- remover as well. HCFC-141b has following characteristics:

1. Chemical Stability: It can be stored at room temperature without decomposition.

2. Dissolvability: It can dissolve in most organic solvents, alcohol and ether. It has excellent compatibility with grease and lubricant, and no obvious effects on most polymers including plastics and rubbers.

3. Toxicity: The toxicity trials conducted by Allied Signal and Atochem indicate that it has no irritant effect on hum an skin and eyes, but inhalation of high-concentrated HCFC-141b will cause anaesthetic effect.

4. Flammability: HCFC-141b is inflammable, it should be stored in ventilated place without flame.
