Features Of Yida MTEG Tetraethylene Glycol Methyl Ether

  1. High purity (>99.0%) with low water content for consistent performance in sensitive formulations.

  2. Excellent solvency for resins, dyes, and polar organic compounds across a broad temperature range.

  3. Low volatility and high boiling point (≈278–282 °C), enabling extended process stability and reduced VOC emissions.

  4. Good miscibility with water, alcohols, ketones, and hydrocarbons — ideal for co-solvent systems.

  5. Non-corrosive to common stainless steel and lined equipment under standard handling conditions.

Typical Applications Of Yida MTEG Tetraethylene Glycol Methyl Ether

  1. Coating and ink formulations — as a reactive diluent and viscosity modifier in UV-curable and high-solids systems.

  2. Electronic cleaning agents — for residue-free removal of photoresists and fluxes in semiconductor manufacturing.

  3. Agrochemical adjuvants — enhancing active ingredient solubilization and foliar penetration in pesticide concentrates.

  4. Specialty polymer synthesis — serving as a chain-transfer agent or reaction medium in polyether-based elastomers.

  5. Gas treating solutions — as a selective solvent for acid gas (CO₂/H₂S) absorption in natural gas purification.
