DESCRIPTION OF DIMETHYL ETHER( DME)

Used as refrigerants and blowing agents
Used as the basis of organic chemical raw materials and power generation

as a propellant in aosol industry

As a substitute for liquefied petroleum gas
the advantages of Dimethyl ether using for civilian fuel are as follows:
Because there is oxygen atom in the DME molecular, so the combustion is secure, and no carbon left after the process, no black smoke, no residue, and the exhaust gas can meet with national standards.
DME is easy compressed, stored at normal temperature ,and the storage pressure is less than the liquefied petroleum gas, so it is more secure, which can also make use of the existing liquefied petroleum gas cylinders, tank or other containers and pipes, kitchen stove can also be universally used, so it is easy to put into daily life use.
As other civilian fuel blending components
adding a certain amount of dimethyl ether into the Liquefied petroleum gas, to resolve the gas supply shortage, reduce the CO content of city exhaust gas, which can also increased the gas burning security and gas calorific value.
Dimethyl ether in fine chemical applications

Dimethyl ether(DME) as a new basic chemical raw materials, because of its good compression, condensation, vaporization, dimethyl ether specilizing in pharmaceutical, pesticide, and fuel, chemical industry and has lots of practical use.

Dimethyl ether 's advantage
1 good quality
2 reasonable price
3 our annual production capacity is high
4 Reliable reputation
