Its estimated that over 100 million gallons of fluids leak from hydraulic machinery and other lubricant equipment in North America each year! 0000000549 00000 n Synfluid PAOs also have a very high degree of saturation, which in lubricants provides oxidative stability. PAOs help to balance the protection and energy conservation requirements in equipment because they are more Newtonian than mineral oils. These products are acceptable for use as a lubricant (H1) or as a lubricant component (HX-1), with incidental food contact in and around food processing areas. High temperatures can thin and break down oil, crippling its lubricating ability, whereas low temperatures can rob a lubricant of its ability to reach critical parts. The superior benefits of PAOs enable formulators to meet these challenges. In both cases, the reduction in volatility will translate to lower oil consumption and reduced engine varnish over the life of the oil. In our experience, some commercially available additive packages are designed to take better advantage of a specific base stock. The chart below shows rotary bomb (ASTM D2272) results between Synfluid PAOs and some mineral oils. Tiny bubbles these can cause major issues, such as shorter lubricant life, increased fluid compressibility, lower fluid viscosity and cavitation. Its great to have the opportunity to talk about both. However, Synfluid PAOs can be formulated to be biodegradable and are well known for standing out from conventional base oils. If a polyurea-based thickener is chosen in conjunction with a synthetic base oil, such as a polyalphaolefin (PAO), there is no compatibility risk to be expected. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. Typically, as the viscosity drops, the volatility increases. The VI of Synfluid mPAO 40 and 100 cSt is 170 and 194, respectively. 0000001216 00000 n startxref This is a far greater benefit than can be achieved from other base oils.
