1,1-Dichloro-1-fluoroethane is mainly used as a solvent and foam blowing agent under the names R-141b and HCFC-141b. It is a class 2 ozone depleting substance undergoing a global phaseout from production and use under the Montreal Protocol since the late 1990s.

Forane ® 141b is a liquid blowing agent ideal for spray foam applications. Since it is a liquid at atmospheric conditions and has low vapor thermal conductivity, which allow the production of polyurethane foam with excellent physical properties.

Forane (R) 141b Emergency Overview Potential Health Effects Clear, colorless liquid and vapor with faint ether odor WARNING! VAPOR REDUCES OXYGEN AVAILABLE FOR BREATHING. HARMFUL IF INHALED AND MAY CAUSE HEART IRREGULARITIES, UNCONSCIOUSNESS OR DEATH. NON-FLAMMABLE VOLATILE LIQUID WHICH MAY CAUSE EYE IRRITATION …

R-141B is a non-flammable refrigerant obtained from Pennwalt Co. as a substitute for R11. It specifically used in leaning and foaming as well as blowing applications. The major purpose of its introduction in the field of refrigerant happened because of environmental degradation.

May 6, 2022 · Countries are reporting that production and use of the ozone-depleting substance hydrochlorofluorocarbon-141b (HCFC-141b) has fallen since 2013.
