Since this can be achieved without sacrificing hydrolytic stability, the finished lubricant will maintain superior properties over an extended period of time, resulting in less waste. One application in which they have not worked well is in high-temperature (high-pressure) reciprocating air compressors where valve deposits have been an issue.
This difference in polarity impacts many lubricant properties including elastomer compatibility, paint solvency, deposit control, and lubrication. and PAO plays an integral part of meeting the challenge for top-tier oils. The chart below shows how Synfluid PAOs can help meet these challenges with the excellent volatility properties of our PAO 5, 7 and 9 cSt grades. They may also be used in applications and areas that may result in incidental food contact or on equipment where there is a potential exposure of the lubricated part to food, such as on food processing equipment as a protective anti-rust film. 0000080859 00000 n

Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. Compatible with seals and paint used with mineral oil, no need for change at all operating temperatures. This process creates a polymer backbone where oxygen is every third atom, which gives PAG basestocks their distinctive chemical attributes and allows formulators to synthesize various combinations of starters and monomers (block, random, and homopolymer) to create custom basestock types for specific applications. After all, the reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants.
PAG lubricant basestocks can be designed to be water-soluble, water-insoluble (partial mineral oil compatibility), or oil-soluble, depending on the selection of starter molecules and monomers to be used in producing the polymer. The chart below shows specific properties of four of our PAO grades that are well-suited to metalworking applications. We have measured a 25 percent improvement in oxidation induction times simply by decreasing the test temperature by 10 degrees. 0000000016 00000 n
Chemical kinetics tell us that if you reduce the temperature, you will reduce the reaction rate. Chemical Compatibility Guide Additives will increase the overall viscosities; however, PAO base oil leaves plenty of room for meeting specifications. Its great to have the opportunity to talk about both. With regard to performance, PAOs are able to maintain excellent thermal and oxidative stability at high operating temperatures in addition to the low-temperature benefits for which they are known. For instance, a 100 percent aminic antioxidant package will yield the best performance in the Rbot test for PAO. No matter what the combination of additive or base oil, one thing is certain: When you begin with a higher-quality base oil, you will achieve a better formulation in the end. These advantages are achieved without the need for VI improvers or other additives, which may promote other deleterious effects as they degrade. All rights reserved. 0000007470 00000 n
A grease formulated with Synfluid PAO and OMGs Calciplex grease precursor could yield a multipurpose product, which allows for consolidation of your grease inventory. Each 10C temperature rise can reduce oxidative stability by half. When you compound this with difficult operating conditions, such as extreme temperatures, high loads or extended operations, a high-quality base oil may be necessary. This is one clear benefit of using a carefully designed base oil. Heres an overview of our production process: Copyright 2023 Chevron Phillips Chemical Company LLC.

Their polymerization can benefit greatly from the development of highly active and highly selective catalysts, as the catalysts strongly affect their properties. 0000001216 00000 n
Since there are no other discernable compounds, Synfluid PAOs are more readily biodegradable and can be used for some food applications. The chart below shows biodegradation test results for Synfluid PAO 2.5, 4 and C12 Dimer, which indicate that these products could qualify as inherently biodegradable according to the ASTM D5864 test method. PAO quality is unrivaled in the industry. For other applications, PAOs safe and non-toxic nature allows it to be used where incidental food contact certification or kosher approval is necessary.
