Features Of Domestic Diethylene Glycol Dimethyl Ether

  1. High purity (>99.5%) with low water content (<0.1%), ensuring consistent performance in sensitive chemical processes.

  2. Excellent solvency for polar and non-polar compounds, enabling broad formulation compatibility.

  3. Low volatility (boiling point ~162–164 °C) and high flash point (63 °C), enhancing handling safety and storage stability.

  4. Good thermal and hydrolytic stability, maintaining integrity under extended processing conditions.

  5. Non-corrosive to common metals and compatible with most elastomers and plastics used in industrial equipment.

Typical Applications Of Domestic Diethylene Glycol Dimethyl Ether

  1. Lithium-ion battery electrolyte solvent for cathode slurries and electrode coating formulations.

  2. Reaction medium in organic synthesis, particularly for Grignard, lithiation, and condensation reactions.

  3. Co-solvent in high-performance coatings, inks, and adhesives to improve flow, leveling, and substrate wetting.

  4. Carrier solvent for agrochemical active ingredients requiring enhanced bioavailability and formulation stability.

  5. Cleaning agent for precision electronics and optical components due to its residue-free evaporation profile.
