Oil formulas to specifically addressed: oil formulation means that the formulation must be oil resistance as the first performance of the formulation.

 

Rubber O-ring, according to the classification performance will be relatively reasonable. Such as: wear indicators do first index formula, with which the products are wear first. Oil, acid, high temperature resistance, chemical resistance, high pressure resistance, water vapor and so on and so on.

 

With the progress of science, often using blends, several grafting techniques and new materials to obtain a low-cost, superior performance formula. This modern economic commodity competition, is also essential. So, between the rubber formulations in value engineering and business benefits of the rubber O-ring, with the strongest determining function.

 

Oil resistance, in the course of chemical stability. If the chemical stability below standard, because the chemical structure of the rubber effect of the oil medium is changed, resulting in other physical properties change: such as strength, deformation, hardness, elasticity, performance degradation, or is completely lost. Thus, the oil resistance is the first performance of the formulation.

 

Depending on the nature of the characteristics of the medium oils, such as: polar oils, nonpolar oils, oils and other temperature conditions. To determine the level of oil resistance. Different levels of the rubber O-ring, to choose a different subject rubber materials. Such as: medium oil is used at room temperature, nitrile rubber can guarantee; If you are using under high temperature conditions, we must choose silicone rubber, fluorine rubber.

 

Press the rubber O-rings of different scope, there are different requirements, the above formula can do Cot. Lining transition used, the excess sulfur can penetrate into the surface of the plastic go, curing time can be vulcanized rubber roller can be controlled. If you do the battery shell, clarinet accessories, and other man-made jade, it is necessary for a long time a secondary vulcanization.
