Arcol Polyol PPG-4000 Polypropylene glycol 25322-69-4 Bayer MaterialScience Polyurethane (PU) - Polyols >> Polyether Inks PPG-4000 is a 4000 molecular weight polypropylene glycol used in a broad range of urethane and other applications. This polyol is one of a series of propylene oxide adducts of diol starters. The material contains only secondary hydroxyl groups and thus has slow controlled reactivity. This polyol is compatible with most polyether polyols and can be blended with other diols or triols to achieve desirable modifications of product properties. PPG-4000 has potential utility in various application areas includ-ing: Caulks, Sealants, Deck and Sports Coatings, Deck and Sports Flooring, Inks, Lubrication, Metalworking, Antistatic Agents, Crude Oil De-emulsification and Plasticizers. Propylene oxide adduct of diol starters. Used in deck and sports coatings and inks. Contains secondary hydroxyl groups. Offers slow controlled reactivity and compatibility with most polyether polyols. Can be blended with other diols or triols.
