And its price is higher relative to mineral oil based lubricating oil, polyether oil etc..Polyether polyol and referred to as polyethers (PAG),
It is carried out by monomer of ethylene oxide, propylene oxide or its mixture using the compound containing active hydrogen group as initiator
Polymer made from ring-opening polymerization.Expressive force of the polyether oil in terms of oxidation stability is not fine, the phase of polyether product
Capacitive is nor very good, and poor with the being mutually dissolved property of mineral oil and synthetic oil, the traditional commercial synthesis of polyether oil uses
Be ethylene oxide, propylene oxide homopolymerization or copolymerization, these materials of tracing to its source still come from mineral oil.Vegetable oil plant oil
It is natural organic-compound easily biological-degradable, itself has very excellent lubricity again, is ideal base oil, but plants
Object oil is a kind of Unsaturatcd fatty acid glycerides, containing a large amount of carbon-carbon double bond, causes its oxidation stability poor, it may occur that
Very serious oxidative phenomena, and more easy to foaming than mineral oil, these defect factors limit oily based on vegetable oil
