Some specially designed polyethers is used as the base oil and thickener of water glycol flame-retardant hydraulic fluids. It is used in HFC systems. It is a high-viscosity water-soluble product that provides lubrication for fluid power,This type of polyether has the following characteristics:
(1) High viscosity, low volatility, suitable for high temperature environments;
(2) Highly clear liquid, non-flammable and non-corrosive;
(3) Excellent cleanliness, no residue or tar;
(4) Excellent lubricity provides good oil film strength;
(5) Shear resistance and long life;
(6) Stable viscosity and cloud point;
(7) Easy to configure, low foam, and meets the common needs of low-pressure systems;
