Dimethyl ether DME has a wide range of applications, including solvents, aerosols, foaming agents, extractants, etc. High purity dimethyl ether can also be used as an anesthetic. When used as a fine chemical product, it can replace traditional chlorofluorocarbons as environmentally friendly propellants. The solubility of dimethyl ether is similar to that of chlorofluorocarbons

R134a refrigerant is a commonly used refrigerant in many air conditioning applications. Due to its characteristics as an HFC (hydrofluorocarbon) refrigerant, R134a has extremely low ozone depletion potential and low-temperature chamber effect. R134a is an excellent alternative to R12, which has been used in various applications. Due to the reduced environmental impact of R134a, the demand for R134a refrigerant and other HFCs will steadily increase. It is also commonly used in modern car air conditioning systems now. Manufacturing is used for plastic foaming. It is used as a propellant in the pharmaceutical industry. When exposed to the atmosphere, it exists in gas form because the boiling temperature is -26.1 ° C.
