What refrigerant is R141?

R141b is a colorless and transparent liquid with high purity, which is no different from odor. It is widely used in the field of plastic foam. Because of its excellent properties, such as low gas-phase thermal conductivity, and compared with R11, R141b's damage to the atmospheric ozone layer is one tenth of that of R11, so R141b has been selected as an ideal substitute for fully halogenated CFCs. R141b can also be used as an advanced industrial cleaning agent and foaming agent to replace R11 and R113.

according to the Montreal protocol, the use period of R141b in developed countries is until 21, but it has been banned in the United States, Japan and other countries. In developing countries such as China, the service life can reach 24, and China has promised to advance it to 23. ?
