The environmentally friendly blowing agent/propellant gas solution with high solvency power is Dimethyl Ether (DME) against chlorofluorocarbon gasses which have adverse effects on the environment.
Dimethyl Ether (DME) consumption in the EU is rapidly growing and becoming prevalent. Dimethyl Ether (DME) can be used in pure state or blended with other propellants.
- Superiorities of Dimethyl Ether
- It is classified as ‘’Non-Ozone Depleting’’ in Montreal and Kyoto Protocols.
- It is classified as non-hazardous to human health.
- Dimethyl Ether (DME)’s low flammability characteristics allow formulators to develop products requiring minimal volatile organic compound emissions.
- Superiorities of Dimethyl Ether (DME) in commercial applications include ability to blend with water thoroughly and homogeneously, high solvency power and high propellant force.
Thorough & Homogeneous Blending with Water:
The outstanding superiority of Dimethyl Ether (DME) lies in its ability to blend thoroughly and homogeneously with water. Therefore, the consumption of Dimethyl Ether (DME) with water is preferable in aerosol industry. When due corrosion precautions are taken, water will not cause problems and it will be easy to maintain the stability of end-product quality.
Dimethyl Ether (DME) forms a single phase, clear and homogenous blend with water and Dimethyl Ether (DME)/Water blends eliminate the feeling of wetness in aerosols.
High Solvency Power:
Dimethyl Ether (DME)’s superior solvency power allows for various design alternatives in aerosol products such as hair sprays and spray paints which require ‘Film Layer Formation’ after application.
Properly formulated spray paints contain optimal amounts of ingredients to dissolve resin and pigments in its contents. They also contain required amount of fast-vaporizing additives to form appropriate film layer after application.
Compared to hydrocarbons, Dimethyl Ether (DME) has superior solvency power. A superior solvent enables less alcohol consumption resulting in higher performance products.
High Propellant Force:
Dimethyl Ether (DME) has a low boiling point and a high vapor pressure. Dimethyl Ether (DME) achieves higher propellant power and higher physical performance in products like paint sprays, air sprays and deodorants, resulting from the unique feature of Dimethyl Ether (DME) passing from liquid phase to gas phase in a much shorter span of time compared to hydrocarbons.
