R141b（R-141b,HCFC-141b,F-141b,dichloromonofluoroethane) is a high-purity colorless and transparent liquid that has no odor. Due to its excellent properties such as low vapor phase thermal conductivity, it also works withR11Compared to
R141b destroys the atmospheric ozone layer equivalent to one-tenth of that of R11, so it was selected as an ideal substitute for fully halogenated chlorofluorocarbons.
R141b Applications
R141b has a wide range of applications in the field of plastic foam. R141b can also be used as an advanced industrial cleaning agent and blowing agent to replace R11 and R113.R141b Advantages
R141b has excellent properties such as low gas-phase thermal conductivity. Compared with R11, R141b's damage to the atmospheric ozone layer is equivalent to one-tenth of that of R11. Therefore, it was selected as an ideal substitute for fully halogenated fluorocarbons. According to the Montreal Agreement, the use period of R141b in developed countries is until 2010. 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.R141b Storage and transportation
R141b steel cylinders are pressurized containers. When stored, they should be kept away from fire, heat sources, and avoid direct exposure to the sun. They are usually stored in a cool, dry and ventilated warehouse; they should be loaded and unloaded with care during handling to prevent cylinders, valves and other accessories from being damaged.R141B parameter
