Polyethylene Oxide (PEO), also sometimes called polyethylene glycol (PEG), are high molecular weight water soluble polymers. PEO polymers are used as thickeners, lubrication aids, film formers, flocculants and binders in applications including adhesives, coatings, inks, water treatment, ceramics, papermaking, agrochemicals, and electronics. Solutions of PEO have a high degree of wet tack and lubricity. PEO falls under the POLYOX™ line of products from Dupont.
