POLYETHYLENE GLYCOL - PEG

PRODUCT DESCRIPTION A thermoplastic polymer obtained by the polymerization of ethylene oxide; the various types of PEG vary according to their average molecular weight, from which they take their name. PEG is soluble in water and in most organic solvents, but with the increase of its molecular weight, solubility and hygroscopicity decrease. The most recognized application of polyethylene glycols is the consolidation of waterlogged wood.
