We have found that Synfluid metallocene polyalphaolefins (mPAOs) not only have low foaming characteristics, but they also exhibit rapid air release when compared to traditional high-viscosity PAOs. We have measured a 25 percent improvement in oxidation induction times simply by decreasing the test temperature by 10 degrees. Technical White Oils are approved for incidental food contact at USDA-approved meat and poultry plants. PAOs derived from 1-dodecene can improve many properties, including volatility. 101 0 obj The degree of the advantage may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). To improve seal compatibility of PAO-based lubricants, an ester is added to the formulation to add some polarity. / A drop-in replacement for petroleum, it's used in countless applications in many industries. PAG-based lubricants are commonly used in compressors, gearboxes, air conditioning systems, metalworking, quenching, and hydraulic systems where fire-resistance or environmental acceptability are required. Since they are fully synthetic, Synfluid PAOs are extremely pure and provide inherent benefits in oxidative stability and viscosity performance at temperature extremes. The chart below shows rotary bomb (ASTM D2272) results between Synfluid PAOs and some mineral oils. Effect of Base Oil Type on Gear Box Temperatures. The vast number of high-quality base oil choices can be confusing when balancing fuel efficiency and wear protection. 169 0 obj It is possible to get added property benefits from C12-based Synfluid PAOs. Polyphenols are a complicated group of plant-based chemicals. More importantly, however, was product performance. The information from such third party sources is believed to be reliable and accurate; however, Purchaser should make its own determination of compatibility before using any SpillTech product. This is a far greater benefit than can be achieved from other base oils. The direct feedstock (normal alpha olefin - NAO) is produced through the chain growth and displacement process for producing petrochemically pure alpha olefins. Chevron Phillips Chemical has been producing two families of PAOs for close to 25 years. endobj PAO-based lubricants offer a significant advantage in oxidative stability. PAO- and PAG-based lubricants are both hydrolytically stable and have low pour points. Since PAO fluids are synthetic hydrocarbons, they are compatible with and often combined with mineral-based oils. 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. Therefore, at high temperatures, it is advantageous to utilize a more stable base oil, specifically Synfluid PAO. endobj Furthermore, we are able to achieve these properties with non-decene alpha olefin feedstocks while providing advantages over existing products and extending feedstock supply. Meet additional regulations (fire-resistance, environmental acceptability). The relative availability of olefin monomer was certainly a consideration (i.e., 1-octene vs. 1-decene).
