Dipentaerythritol fine powder

CAS NO. : 126-58-9
Molecular formula:C5H12O4

Di-PE is a white, odor less and crystalline powder. It’s slightly soluble in water, but little soluble in most organic solvent.
Di-PE, as an important fine-chemical intermediate, it is mainly used in used in the manufacture of resins, plasticizers, synthetic lubricants, rosin esters and Acrylic monomers for UV curing system. And also for top intumescent coating.
