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. Chevron Phillips Chemical has consistently said that we would bring something to the market when we could provide products that are unique and offer advantages to our customers. In addition to these advantages, kosher certification for Synfluid PAOs is available upon request. There are other advantages, such as oxidative and thermal stability, which you would naturally expect from a PAO-based product. These excellent pour points are achieved while increasing the viscosity indices (VI) over traditional HV PAO. One example is the advantage PAO has over mineral oil in the area of high-temperature stability. The second step is the hydrogenation of the remaining double bonds (unsaturation) in the oligomer and subsequent distillation to separate the unreacted monomer and light-viscosity grade PAO. Since we are all concerned with the protection of our environment, it is important to note some PAOs can be formulated with other components into biodegradable fluids. hb```f``g mBU L4#o0 D The chart differentiates the blending capabilities of various base oils to meet energy-efficient motor oils. The chart below shows the effect of two different shear rate viscosity determinations on three different fluids (4 cSt at 100C) and the dramatic differences between them. To improve fuel economy, OEMs are moving toward lower-viscosity oils, even in heavy-duty diesel engines. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. They are also employed as base fluids in some wide temperature range greases. In addition, a PAO-based multi-purpose grease can be formulated to be both H1 and kosher approved. For instance, many producers have tailored production to Group II+ stocks at 118119 VI, just below the ambiguous Group III limit of 120VI. Meet additional regulations (fire-resistance, environmental acceptability). The challenge presented to a formulator is maintaining the performance levels while achieving biodegradability. The chart below shows that the PAO has a higher specific heat, which means that the PAO is better at absorbing heat.
