Paraffinic types : This class of hydrocarbons constitutes branched chain or straight linked hydrocarbon molecules of various viscosities. As the chain length increases, the viscosity increases and the rubber process oil becomes more viscous. They find extensive usage in EPDM, Butyl rubbers. IPOL grades include Paraffinic oils with high viscosity and high flash point for better shelf life of the end product. The high viscosity and high flash point IPOL paraffinic oils are extensively used in EPDM profiles for automotive applications.
