There are five specific categories of base oils. These categories define the type of base stock the oil is formulated from. The categories are as follows. Note that the base oil group category is followed by the manufacturing method (in bold print) and then a description of the oil characteristics for each category.

Group I - Solvent Freezing: Group 1 base oils are the least refined of all the groups. They are usually a mix of different hydrocarbon chains with little or no uniformity. While some automotive oils on the market use Group I stocks, they are generally used in less demanding applications (hh).

Group II - Hydro processing and Refining: Group II base oils are common in mineral based motor oils currently available on the market. They have fair to good performance in lubricating properties such as volatility, oxidative stability and flash/fire points. They have only fair performance in areas such as pour point, cold crank viscosity and extreme pressure wear (hh).

Gilsonite in Industrial

date_rangeAug 08' 2018 /  Iran

A highly pure natural bitumen is known as Gilsonite Industrial grade. It used to make asphalt floor tiles, storage battery boxes, paints, black varnishes. Also used in hot underground piping, waterproof coatings, wire insulation, linoleum and floor tiles, paving, low grade rubber compounds, dark photogravure inks, solvent-free seam sealers in automobiles. Furthermore, it uses in oil-drilling, foundry, explosive, and nuclear graphite industries.

Oxidized Bitumen 90/15

date_rangeAug 07' 2018 /  Iran

Oxidized Bitumen 90/15 Description Oxidized Bitumen also known as hard bitumen, blown bitumen, bitumen oxide and hard asphalt. It produced by passing air through the penetration grades. This process cases bitumen be more rubbery than its original formula. Oxidized Bitumen 90/15 and other grades are simply harder bitumen.
