Methylene Diphenyl Diisocyanate (MDI) Mix of CAS:26447-40-5 & CAS:101-68-8 Methylene Diphenyl Diisocyanate is produced by a 4 steps reaction based on benzene as feedstock. There are 3 isomers of MDI : 2,2-MDI, 2,4-MDI, and 4,4-MDI. The 4,4 isomer is known as pure or monomeric MDI (mMDI).The Polymeric MDI so called Crude MDI contains monomeric MDI […]

Polyethylene Glycol (PEG)
Polyethylene Glycol (PEG) is a clear, colorless, viscous liquid soluble in water.
Liquid PEG are soluble in acetone, alcohols, benzene, glycerin, and glycols.
Solid PEG are soluble in acetone, dichloromethane, ethanol (95%), and methanol; they are slightly soluble in aliphatic hydrocarbons and ether but insoluble in fats, fixed oils, and mineral oil.
Polyethylene Glycol Chemical Structure Composition.
Production
Polyethylene glycol (PEG) is formed by the reaction of ethylene oxide and water under pressure in the presence of a catalyst.
Uses
Polyethylenglycol is used in a variety of applications such as : skin creams, toothpastes, surfactant, detergent, pharmaceutical formulations, electronics as insulator, polymer, antifoam agent, ceramics.
