DME (Dimethyl ether)

DME  (Dimethyl ether) is a colorless, odorless gas that is used as a propellant in aerosol cans. It is also used as a blowing agent in the production of polyurethane foam. DME is alternative to other propellants, such as chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs). It is a safe and effective propellant that is a good choice for a variety of applications. The gas is non-toxic, and biodegradable. It is also more efficient and cost-effective than other propellants. It is also more environmentally friendly, as it does not contribute to ozone depletion or global warming.
