Polyols There are two major kind of polyols used in Polyurethane : polyester polyols and polyether polyols. Polyester polyols are produced by reacting acid and glycol. Main acids utilized are Adipic, Isophtalic, Terephtalic, Succinic, Sebacic Main glycols utilized are MEG, DEG, BDO, HDO, NPG, TMP. Polyether polyols are made by reacting organic oxide and glycol […]

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.
Arpadis is one of the largest chemical distributor in Europe.
Arpadis is handling the storage, transport, export & import formalities of Polyethylene Glycol globally.
