Rubber Process Oils are used during the mixing of rubber compounds. Rubber process oil is an oil composition that has a kinematic viscosity at 100 °C of from 25 to 50 CST and which contains less than 3%. Polynuclear aromatic compounds are employed as a process oil for rubber compounds, especially aromatic rubbers.
Ng-Oil Petroleum Company supplies RPO 245, 250, 290, 840, and DAE.
