Packaging and shipping
Dipropylene glycol dimethyl ether (DMM) is an ether-based solvent with no reactive hydrogen (non-proton) in its molecule. Its unique molecular structure endows it with a series of outstanding properties: extremely high chemical and thermal stability, a wide electrochemical window, excellent solubility, low toxicity and low corrosiveness. This enables DMM to go beyond the application scope of traditional alcohol-ether solvents and become the ideal choice for high-voltage lithium-ion battery electrolytes, precise electronic cleaning, harsh conditions organic synthesis, and special functional fluids in high-end technical fields.

Product Core Positioning
Di-pentyl glycol dimethyl ether (DMM) is an ether-based solvent with no reactive hydrogen (non-proton) in its molecule. Its unique molecular structure endows it with a series of outstanding properties: extremely high chemical and thermal stability, a wide electrochemical window, excellent solubility, low toxicity and low corrosiveness. This enables DMM to go beyond the application scope of traditional alcohol-ether solvents and become the ideal choice for high-voltage lithium-ion battery electrolytes, precise electronic cleaning, harsh conditions organic synthesis, and special functional fluids in high-end technical fields.
Core application value and solutions
High-voltage lithium-ion battery electrolyte (core high-end application): As a key solvent component of high-voltage electrolytes, DMM, with its wide electrochemical window and excellent oxidation stability, can effectively prevent the decomposition of the electrolyte at high voltages, significantly enhancing the energy density, cycle life and high-temperature safety of the battery. It is one of the core materials for developing next-generation high-energy-density power batteries and energy storage batteries.
High-end special cleaning agent (for electronic-grade applications): As an electronic-grade non-proton high-boiling-point solvent, DMM has strong solubility for photoresists, resins, greases, etc., and has extremely low corrosiveness to metals, glass, silicon wafers, etc. It is widely used in the cleaning processes of semiconductor manufacturing, display panels, and precision optical components, as well as in the formulation of photoresist stripping solutions, meeting the strict requirements of high-end manufacturing for cleaning purity and safety.
Pharmaceuticals and Advanced Organic Synthesis: As an ideal solvent for anhydrous and oxygen-free reactions, the chemical inertness of DMM ensures that it does not interfere with the reactions of sensitive metal-organic compounds such as Grignard reagents and organic lithium reagents. It is widely used in key steps such as Grignard reactions, coupling reactions, catalytic hydrogenation, and polymerization, and is an ideal reaction medium for synthesizing high-value pharmaceutical intermediates, pesticides, and special materials.
Functional chemicals and intermediates: The stable ether bond structure of these substances enables them to serve as functional monomers or intermediates themselves, which are used for synthesizing special polymers, ionic liquids, phase transfer catalysts, and various functional materials, thereby expanding their application boundaries in the field of materials science.
Heat transfer and special functional fluids: Thanks to its wide liquid temperature range, high thermal stability, and excellent oxidation stability, DMM can be used as the base fluid for high-performance synthetic heat transfer oil, heat medium, or special hydraulic fluid, and is suitable for industrial fields such as closed-loop heating systems with long-term stable operation requirements, solar thermal storage systems, etc.
