Dimethyl ether

Dimethyl ether (CAS 115-10-6), also known as DME, methoxymethane, or by trade names such as Dymel A and Dymela, is a simple ether with the formula C2H6O. It carries no assigned E-code and is handled as a liquefied gas under pressure. It is registered under REACH and assigned EC number 204-065-8.

In oil and gas operations, DME functions as a solvent and carrier for chemical injection fluids, dissolving treatment additives and transporting them into wellbore systems. In polymer manufacturing, it acts as a polymerization initiator, controlling reaction onset in specific aerosol and foam formulations. Automotive and aerospace applications use it as a propellant carrier solvent in precision cleaning and coating processes.

DME is supplied as a liquefied gas in pressurised cylinders and bulk containers, with grades available to meet industrial and technical specifications. It falls under REACH regulation and requires standard compressed gas handling compliance across EU member states. Buyers should confirm purity grade requirements prior to ordering.
