1. Synthetic Hydrocarbons of GTL(Gas to liquid) - We believe that this GTL petroleum is synthetic in name only; if it were truly synthetic, it wouldn't have any sulfur in it (OCP modified their allowable sulfur recommendation because the Shell oil has so much in it). This is just Shell's new oil refinery in Qatar that they're desperate to fill up to capacity.
2. Synthetic Hydrocarbons of PAO(Poly-alpha-Olefin) - This is the closest OCP category to our products.
3. Synthetic Esters - Synthetic esters are great for lubricants, but they are not suitable for datacenter thermal management because of their terrible material compatibility profiles. Esters (both synthetic and natural) are "plasticizers", which means that these chemicals are used in plastic formulations to keep them flexible. This means that esters are not compatible with a wide variety of elastomeric materials; they become too soft and mushy.
4. Natural Esters - Natural esters are another name for "vegetable oil". In addition to the material compatibility problems outlined above, vegetable oils have the problem of rancidity and terrible oxidation stability.
5. Biobased Renewable Hydrocarbon - There are only a few examples of these new fluids available; their long term stability is unknown, their material compatibility profile is unknown, and they're expensive. Most are made from algae or grasses.
6. Perfluorocarbons (PFCs) - Not sure why OCP even includes this category of fluid. PFCs are all Perfluoro Alkyl Substances (PFAS), which are being restricted and banned worldwide because of their well-known environmental and health problems. These fluids won't be commercially available anymore in a few years.
