Give us a call, and well be glad to discuss your applications and provide technical help. Synthetic basestocks, more so than in mineral oil basestocks, are the primary contributor to most of the basic properties of the lubricant, including oil or water solubility, low-temperature fluidity, lubrication, volatility, ignitability, and seal and paint compatibility. The viscosity of the base oil is largely irrelevant in relation to the compatibility risks with the thickener. The limits on lowering the viscosity grade are tied to the base oil properties. One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. Better heat transfer coefficients, increased lubricity and the basic chemical structure of PAOs all contribute to the lower temperature in the gearbox. The vast number of high-quality base oil choices can be confusing when balancing fuel efficiency and wear protection. Specifically, soybean-derived oils or other bio-derived oils alone would not meet some oxidative stability and low-temperature performance requirements. P.V.C. The more EO monomer in the basestock, the more water-soluble; the more PO monomer, the more water-insoluble; and the more BO monomer, the more oil-soluble the basestock is.
