Product Characters

• Under normal temperature and pressure, dichlorofluoroethane (HCFC-141b) is a non-toxic and colorless chemical with low ODP value and excellent chemical stability;
• It shows good chemical stability, can be stored at normal temperature without decomposition;
• Even being boiled, it does not corrode iron, stainless steel, copper, brass, aluminum and zinc, etc.;
• It is soluble in most organic solvents, alcohol and ether. It has excellent compatibility with grease and lubricant, has no obvious in effects on most polymers including plastics and rubbers;
• The toxicity trials conducted by the international society PAFT 11 indicates that it has an irritant effect on human skin and eyes, but inhalation of high-concentrated HCFC-141b will cause anesthetic effect.

Main Application

• Since its physical and chemical properties are similar to those CFC-11, CFC-113, it can replace CFC-11 as foaming-agent for rigid or soft PU foam, or it can be a substitute for CFC-113 as metal cleaner and solder remover as well. It is a worldwide acknowledged CFCs substitute. 

Packing, Storage & Transportation

• Packed in iron drum. It should be stored in cool, dry and ventilated place, and kept away from sunlight and rain.
