PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. High energy costs have hit both businesses and consumers hard, and the pressure is on to conserve. Getting the air to release from the lubricant is vital to allowing the lubricant to do its job. The PAOsare produced through synthesizing oligomers of either 1-decene or 1-dodecene. The lighter components cause poorer volatility properties as well as lower flash and fire points. It is a synthetic hydrocarbon (SHC) that mimics the best hydrocarbon (branched) structure found in mineral oils. 0000013783 00000 n
Therefore, at high temperatures, it is advantageous to utilize a more stable base oil, specifically Synfluid PAO. The chart below shows that the PAO has a higher specific heat, which means that the PAO is better at absorbing heat. Additives will increase the overall viscosities; however, PAO base oil leaves plenty of room for meeting specifications. 0000001211 00000 n
As the viscosity grade decreases, the volatility and high-temperature/high-shear viscosity will be limiting factors. By utilizing this new process combined with the inherent properties of PAOs, a grease can be produced that can be used in both extreme high- and low-temperature applications. 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.

The viscosity of the base oil is largely irrelevant in relation to the compatibility risks with the thickener. Using Chevron Phillips Chemical Synfluid PAOs, OM Group (OMG) has developed a revolutionary new, lower-temperature, abbreviated process for producing greases. Benefits of the new system are a much higher viscosity index (VI), superior pour points and improved low-temperature fluidity, all of which contribute to improved energy efficiency. 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. Two lubricants with the same VI may perform dramatically differently at low temperatures. A polyolefin is a type of polymer with the general formula (CH 2 CHR) n where R is an alkyl group. Specific heat is the amount of heat per unit mass required to raise the temperature one degree Celsius. Focusing on the components of the additive package can further influence the performance of the formulation. This clearly shows that a PAO base oil substitution can significantly lower operating temperatures of the gear box and extend the required maintenance interval. The effects of the shear rate differences are even more exaggerated at low-temperature startup conditions, when the lubricant function is critical for equipment protection. The uniquely beneficial quality of PAOs has been demonstrated in a series of European engine tests. Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications. Synfluid PAO 5 and PAO 7 also offer several advantages in addition to the volatility, such as low pour point, high viscosity index, improved oxidative stability and excellent low-temperature viscosities.
