SYNALOX Water Soluble Lubricant Base Stocks

EO/PO Random Copolymers

SYNALOX* Water Soluble Lubricant Base Stocks are random copolymers of ethylene oxide and propylene oxide. This family of polyglycols is soluble in cold water, but exhibits inverse solubility at high temperatures. Water based solutions provide low surface tension, good wetting and good penetration characteristics, while also exhibiting low foaming properties. Water soluble SYNALOX Fluids are extensively used in formulations for chemical fiber spin finishes and industrial lubricants. For example, SYNALOX 50-30B and SYNALOX 50-50B are key base stocks for spin finish lubricants in the production of textured polyester and nylon yarns. Dow offers an extensive viscosity range of water soluble SYNALOX Fluid grades from ISOVG 22 to 1000.
