Description

Dimethyl ether ( CAS 115-10-6 ), also known as methyl ether, is a compressed liquefied gas used across aerosol, energy, and industrial manufacturing sectors. It functions primarily as a propellant, solvent, and fuel component. This chemical offers clean combustion and high vapor pressure that drive its adoption in both consumer and industrial applications. In home care and personal care aerosols, it acts as a propellant and co-solvent. It enables consistent spray delivery in products such as household cleaners, air fresheners, and surface treatments. The oil and gas sector uses it as an alternative fuel and fuel blending component for various systems. Its high cetane number supports diesel substitution and LPG blending programs. In plastics and polymer manufacturing, it serves as a foam-blowing agent and polymerization initiator carrier for industrial use. This is particularly useful in the production of polyurethane foams. Aerospace and defense applications include its use as a cold-start fluid and precision cleaning solvent where rapid evaporation is required. It is valued for residue-free performance in sensitive environments. Dimethyl ether is supplied as a liquefied compressed gas in pressurized cylinders, ISO tanks, and bulk tanker deliveries for global shipping. Aerosol-grade and fuel-grade specifications are the most commercially prevalent, with purity levels typically ranging from 99.0% to 99.9%. Packaging options are selected based on downstream application requirements. All logistics are handled according to regional transport regulations. This ensures the material maintains its integrity from the production facility to the final industrial or commercial destination. Contact us for supply of Dimethyl ether Request Quote
