          Application:

          1.PPG series are soluble in methylbenzene, ethanol and TCE organic solvents. PPG200, 400 and 600 are soluble in water with performance of lubricating, solubilizing, defoaming and antistatic. PPG-200 can be used as dispersing agent of dyestuff.
          2.In cosmetics, PPG400 can be used as emollient, softener and lubricant.
          3.Used as defoaming agent in paint and hydraulic oil, synthetic rubber and latex; as freezing agent, coolant and viscosity improver in heat transfer fluid.
          4. Used as intermediates for esterification, etherification and polycondensation.
          5. Used as release agent, solubilizer, additive for synthetic oils and water soluble cutting fluid, roller oil, hydraulic oil and high temperature lubricant, internal and external lubricants for rubber.
          6. PPG-2000~8000 has properties of lubricating, foam resisting and heat & cold resisting.
          7. PPG-3000~8000 is mainly used component of polyether and can produce polyurethane foaming plastic.
          8. PPG-3000~8000 can be used directly or etherified to make plasticizer and lubricant.
          9. This series can be used as base material for daily chemicals, pharmacy and oiling agents.
