Polyoxymethylene Dimethyl Ethers PDM Solvent Substitute for PMA
Product Description
PDM, Polyoxymethylene Dimethyl Ethers(Dioxydimethyl Ether Acetate), is used as coating solvent and diesel fuel additive as well. It has greater solubility than arenes, and owns amphipathic property. Thus it can easily dissolve other solvents and resins, highly reducing the unpleasant odor.
The average cetane number is 76 and the quality of blended diesel with PDM (blending ratio between diesel and PDM is 85 to 15) is better than ultra-low-sulfur diesel. By comparison, the combustion efficiency can be improved for the blended diesel, the emissions of PM2.5 and CO can be reduced largely, and off-gas pollution can be cut by more than 50%.
