Tetraethylene Glycol Dimethyl Ether is a clear, colorless liquid that is water soluble. Tetraethylene Glycol Dimethyl Ether can be used as excellent solvent of alkaline metal hydride and it is used in alkyl combination or recycle chemical reaction. As Tetraethylene Glycol Dimethyl Ether has Louise alkalinity, it can electively absorb acid gas to purify the synthetic gas, natural gas and acetylene.

Applications:

As a strong emulsifier, Tetraethylene Glycol Dimethyl Ether is used in the coatings industry, stabilizes inks and functions as a humectant to prevent clogging of printer heads.

Additionally, Tetraethylene Glycol Dimethyl Ether is used to increase the efficiency of refrigeration systems while also serving as a lubricant due to its unique solvency parameters.

Graphics arts – ink solvents: Tetraethylene Glycol Dimethyl Ether is useful in a variety of ink formulations, including inkjet inks that are stable and do not clog tiny orifices, highend writing inks with low viscosity and good stability, conductive inks and pastes, as well as magnetic inks.

Tetraethylene Glycol Dimethyl Ether is used in ink formulations to:
• Maximize color print quality and durability
• Increase cartridge reliability and endcap/idle times
• Eliminate odor and toxic solvents
• Minimize dispersant and pigment cost
• Choose boiling points to control droplet size and to concentrate dyes on the surface

Key Properties:
• Tetraethylene Glycol Dimethyl Ether is 94% non-VOC by EPA method 24
• High solvency provides stability and maximum color density
• Strongly complexes with pigments
• Low odor
• Prevents inkjet clogging
• Acts as an emulsifier and humectant

Aqueous coating compositions useful in coating substrates immediately after printing with oil-based inks contain Tetraethylene Glycol Dimethyl Ether. These coatings accelerate bonding and drying of the ink, which permits faster printing.

Humectants as strong emulsifiers: The use of Tetraethylene Glycol Dimethyl Ether improves cartridge life and idle (also known as decap) times. Being a strong emulsifier Tetraethylene Glycol Dimethyl Ether is used to stabilize ink and function as humectant to keep orifices clear.

Refrigeration – lubricate and increase efficiency: Tetraethylene Glycol Dimethyl Ether is used to increase the efficiency of refrigeration systems while also serving as a lubricant due to its unique solvency parameters. Tetraethylene Glycol Dimethyl Ether showed high solubility for HFC-134a and newer chlorofluoro-carbons with negative deviations of the pressure vs. mole fraction data from Raoult’s law. HFC-134a had lower solubilities in the other glycols or monoethers tested. Tetraethylene Glycol Dimethyl Ether is also more chemically and thermally stable, in addition to having higher solvency for HFC-134a and similar refrigerants.
• The affinity of Tetraethylene Glycol Dimethyl Ether and HFC-134a was shown by an exothermic heat of mixing of –770 cal/mol at an 0.61 HFC-134a mol fraction.

For Bright and durable Inks: Ink formulators use solvents as key ingredients to improve image appearance and durability. The ability of Tetraethylene Glycol Dimethyl Ether to disperse pigments in aqueous and solvent-based systems enables formulators to reduce cost and increase ink stability. The choice of mix of medium boiling point controls evaporation rate, to keep the pigment or dye concentrated on the paper surface, for maximum color density.
