According to ASTM International, oil gelation is defined by a rheological condition of an oil characterized by a marked increase in the flow resistance over and above the normal exponential increase of viscosity with decreasing temperature, particularly at lower shear stresses and temperatures. ASTM D5133 is one method that can be used to analyze the tendency of oil gelation. In this test, a candidate oil is heated and then gradually cooled while the viscosity is measured at different temperatures. 


The gelation index is a result of this test. As oil is cooled, the viscosity goes up. This value can be plotted on a chart. The slope of the viscosity line versus temperature is analyzed for changes. If the slope rapidly increases at a certain temperature, this should be noted. Once the test is completed, the full chart can be analyzed and the gelation index developed. The temperature at which the viscosity rapidly thickens is known as the gelation index temperature.


This information becomes important as temperatures decline, especially if the equipment operates in a cold environment such as in a freezer or outside in cold climates. Oils most prone to gelation are typically motor oils, particularly those with a higher wax content than others (paraffinic base oils). This phenomenon occurs in colder conditions or in situations where the oil has experienced a gradual cooling. As the viscosity increases due to lower temperatures, certain contaminants or conditions can be achieved in which the viscosity rapidly increases and the oil gels.


 

MANUFACTURING PROCESS OF GEAR OIL is not very complicated. For the production, there is need usable and tried a formulation, ingredients ( performance and another additives, base oils,foam agent, pour point depressant, etc. ) and process tank. For ingredients to be used, quantities to be used and ingredients usage rankings, you should look into this formulation and manufacturing process. Therefore, formulation and productıon process of FULL SYNTHETIC,SEMI SYNTHETIC GEAR OIL are important. If you have not a good formulation, you cannot make healthy and  efficient production of any lubricating oils.
