EO/PO block copolymers (poloxamers) consist of a broad range of versatile, non-ionic surfactants made from ethylene oxide and propylene oxide. Most of them consist of a triblock copolymer with a central polypropylene oxide group flanked by two polyethylene oxide groups. One can also get block copolymers in which the central group is polyethylene oxide and this is flanked by two groups of polypropylene oxide. They are used where antifoaming, dispersing, wetting and emulsifying is required, and are thus used in rinse-aids, hard surface and metal cleaning. They can also find application in agriculture, coatings, etc. |
