After all, the reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. A process enhancement at Chevron Phillips Chemicals manufacturing facility has resulted in up to a 30 percent improvement in oxidative stability when used with aminic antioxidants in Rotary Bomb Oxidation Tests (RBOT). These properties translate into easier distribution of the grease and improved energy efficiency in the equipment. These include PAOs and also relatively common polyisobutenes (PIB), which are sometimes used as oil additives or as base oils in two-stroke engines. Absolutely! This lowers their volatility, creates less hydrocarbon tailpipe emissions and raises the flash point. Furthermore, the arbitrary distinction of 120 VI between Group II and III oils makes the quality requirements even more confusing. The direct feedstock (normal alpha olefin - NAO) is produced through the chain growth and displacement process for producing petrochemically pure alpha olefins. LDPE is defined by a density range of 0.910-0.940 g/cm3. Typically, petroleum-base oils are not synonymous with terms like green or environmentally friendly. polyalphaolefin compatibility chart.

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. <> Chevron Phillips Chemical offers two lines of PAOs. The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. The Ethylene price in the Europe region was dull throughout the third quarter of 2022, which abetted the declining price trend of PAO throughout Q3 in Europe. However, PAGs and PAOs are two totally different chemical types of synthetic base stocks. 0000001493 00000 n Consistent feedstocks give rise to consistent PAO quality, resulting in consistent finished fluid performance. For instance, many producers have tailored production to Group II+ stocks at 118119 VI, just below the ambiguous Group III limit of 120VI. Because a certain level of biodegradability can be achieved without sacrificing PAOs key benefits, a finished lubricant based on a PAO/biobased blend will maintain superior properties over an extended period of time, resulting in less waste. These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile. %PDF-1.4 % trailer <<1656AD0EDA344239AE3641B5710538C3>]/Prev 1036271>> startxref 0 %%EOF 296 0 obj <>stream In drivetrain lubricants, reducing the traction coefficient and lowering viscosity are key ways to increase fuel economy, but lower viscosity must be balanced to provide adequate wear resistance. 0000010623 00000 n Chemical Compatibility Guide The PAOs .

With many new base oils being introduced to the market, lubricant consistency can really be a challenge. Thermal conductivity is the measure of the ability to conduct heat. Synfluid mPAOs exhibit faster air release times, particularly when comparing the 100 cSt blends. High-viscosity PAO fluids have also become popular in industrial fluids and greases. Three stringent test standards required by Volkswagen and Mercedes-Benz engines show the impact of the variability of Group III oils: This data illustrates lot-to-lot variability, which has been recognized for the Group III oils. P.V.C. PAOs offer exceptionally low volatility due to their controlled formation, which yields carefully designed molecular weights. BioPreferred is a registered service mark of the United States Department of Agriculture. Both lubricant types are used in industrial gearboxes, compressors, and even air conditioning systems. Initially, it was intended to fill the gap in supply and was found to be exceptionally suitable for applications where extremely low pour points were not necessary. One example is the advantage PAO has over mineral oil in the area of high-temperature stability. Copyright 2023 Chevron Phillips Chemical Company LLC. PAG basestocks are classified as a Group V oil, meaning a synthetic basestock that is not defined as a Group I, II, III, or IV base oil. Polyalphaolefin does not contain ring structures, double bonds, sulphur, nitrogen components or waxy hydrocarbons. These are areas where PAOs excel. The qualitative chart below describes the impact of each grease component on certain performance characteristics: Clearly, the base oil dominates some grease properties, while the additives or thickener drives others. 4 Chemicals PVC CPVC PP PVDF ABS.
