Details


Polyether has excellent precipitation control and cleaning performance.Excellent low temperature performance. High viscosity index and wide viscosity grade make it widely used in various lubricating interfaces

As a new synthetic base oil and functional agent, the oil soluble polyether is produced by sasol.The traditional PAG and other lubricants have poor solubility, and they are easy to absorb moisture, and have defects such as aging of rubber elastomer.
