HCFC-141b is utilised as a blowing agent for Polyurethane and other insulation foam applications .HCFC-141b has an ozone depleting potential of 0.11 and is being phased out under the Montreal protocol. HCFC-141b is supplied only into those markets  where its use is still allowed under the Montreal protocol.  A-Gas also offers a range of non-ozone depleting blowing agents to help customers transition away from such ozone depleting products.

HCFC-141b is also still used for some specific solvent cleaning applications due to its excellent solvency and non-toxic properties.
