Dichlorofluoroethane BTTRI GAS® R141b is a nontoxic and colorless chemical with small ODP value and excellent chemical stability. Since is 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. It is a worldwide recognized CFCs substitute. BTTRI GAS® R141b has following characteristics: 1. Chemical Stability: It can be stored at room temperature without decomposition. 2. Corrosion: Even being boiled, it does not corrode iron, stainless steel, copper, brass, aluminum and zinc etc. 3. 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. 4. Toxicity: The toxicity trials conducted by Allied Signal and Atochem indicate that it has no irritant effect on human skin and eyes, but inhalation of high-concentrated BTTRI GAS® R141b will cause anesthetic effect. 5. Flammability: BTTRI GAS® R141b is inflammable,it should be stored in ventilated place without flame .
