PAO SYNTHETIC MATERIAL COMPATIBILITY CHART This table is aids in the selection of elastomers, plastics and paints for use in conjunction with PAO synthetic fluids. <>stream Use of WGHFs increased tremendously due to the publication of the Luxembourg Report in 1961, outlining minimum standards for hydraulic fluid fire-resistance in European coal mines. 0000018828 00000 n 0000027693 00000 n General properties of water-soluble, water-insoluble, and oil-soluble PAG basestocks are shown in Table 1. 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. However, PAOs can help. Our customers quickly realized the advantages in volatility, low-temperature viscometrics, VI and flash and fire points in equiviscous blends compared to 1-decene-based materials. Group V oils also include esters and naphthenic oils. The chart below shows rotary bomb (ASTM D2272) results between Synfluid PAOs and some mineral oils. The chart below shows a comparison of the foaming characteristics of our Synfluid mPAO high-viscosity base oils with traditional high-viscosity PAO 40 and 100 cSt base oils. One obvious trend is that low-viscosity oils are beneficial in improving fuel efficiency. general guideline for pump material selection The vast number of high-quality base oil choices can be daunting when trying to balance fuel efficiency and wear protection. From then on, the company introduced 1-dodecene-based PAOs in 1995, which have grown steadily in popularity. These include the tendency to shrink seals and trouble dissolving common oil additives. Softening, loss of strength, or swelling may occur. However, not all synthetic lubricants are created equal. California Transparency in Supply Chains Act Disclosure. xref 0000001605 00000 n You see, PAOs are carefully designed, not refined. However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. 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. Metallocene-catalyzed commercial mPAO basestock grades can attain a viscosity of 300 cSt at 100C. PAOs derived from 1-dodecene can improve many properties, including volatility. Synthetic lubricants can meet these demands because they perform better than mineral oil-based lubricants in many or all the critical performance areas: reduced wear and friction, resistance to sludge formation, lower volatility, greater corrosion protection, and improved thermal and oxidative stability. There are several systems where we have observed a reduction in the operating temperature compared to mineral oils, including transmissions, engines and heat transfer applications. It is a synthetic hydrocarbon (SHC) that mimics the best hydrocarbon (branched, non-ring) structure found in mineral oils and so corrects for many disadvantages of using mineral oil lubricants, including poor low-temperature fluidity, poor viscosity index, sludge deposits, and high volatility. polyalphaolefin compatibility chart - dice-dental.asia Polypropylene Satisfactory to 120 F. 4. Several synthetic base oil types fall into the SHC category. These advantages are achieved without the need for VI improvers or other additives, which may promote other deleterious effects as they degrade. endobj 1 - High Resistance 2 - Limited Resistance 3 - No Resistance . While viscosity improvers can enhance VI, they can break down over time, resulting in diminished performance. The PAOsare produced through synthesizing oligomers of either 1-decene or 1-dodecene.
