Monofluorodichloroethane (HCFC-141b) is a high-purity colorless and transparent liquid that has no odor. It is widely used in the field of plastic foam. Due to its excellent properties such as low vapor phase thermal conductivity, it also works withR11In comparison, monofluorodichloroethane is one-tenth of the damage to the atmospheric ozone layer of R11, so it was selected as an ideal substitute for fully halogenated chlorofluorocarbons. Monofluorodichloroethane can also be used as high-gradeindustrial cleaning agentsandblowing agent, used to replace R11 andR113。
According to the Montreal Agreement,R141bThe use period in developed countries is until 2010, and currently the United States, Japan and other countries have banned its use. In developing countries such as China, the service life can reach 2040, and China has promised to advance it to 2030.
