Paraffin waxes in a solid state are usually white, translucent, tasteless and odorless. They are hard, relatively brittle and have a slightly dry feel. In a molten state, paraffin waxes are clear, colorless liquids of low viscosity. When melted, these waxes increase in volume by about 5-8%, resulting in a decrease in density. Paraffin will react at high temperatures with either oxidizing or halogenating agents. This reaction produces either fatty acids and hydroxy acids or halogen substitution products respectively. Although paraffin has many useful characteristics, most commercial applications are based on its resistance to water and vapor and its glossy appearance when polished.

The main element of lubricants (volume wise) is base oil and it forms about 95% of lubricants weight. In some lubricants (Compressor and hydraulic oil) 99% of the oil is consisted of base oil and only the 1% which is left contains additives. Base oils can be reached from oil based and non-oil based resources. Most of the base oils used in the world are obtained from crude oil refining. Most of the compounds which form base oils are Paraphinic, Naphthenic and aromatic compounds. Base oils chemical properties and their impact on the usage of final lubricant: 1 volatility: reduction of the oil, oil thickening, sediments 2 surface activity: foaming, pressure tolerance, air release, emulsion expansion 3 oxidations: sediments, oil thickening, metal oxidation, mud forming 4 Viscosity: Fluidity in lower degrees, energy waste, abrasion protection, proper cooling 5 being soluble: Motor neatness, sealant compatibility, process applications, formulation sustainability The base oil which is extracted from crude oil is called mineral base oil which is categorized in two types (Paraphinic and Naphtshic). Paraphinic oils are consisted of normal hydrocarbons and Iso hydrocarbons. Naphthic oils are consisted of annular full hydrocarbons. Paraphinic oils have certain attributes in comparison with naphthic oils such as; More shedding temperature Less special weight More viscosity indicators Less solubility property Higher resistance against oxidation Higher flash point Mainly naphthic oils are needed for less temperature criteria and pour point specially; hydraulic oils, coolers, rubber producing oils, metalworking and cylinders lubricants for big motors and greases.
The most important advantage of the on-line style tester is that it can work when the ESP Unit is running. To put it differently, the insulation resistance of the system can be measured without power off and will keep the ESP system running through most common failures.
