Servo Rubbess 12 is a paraffinic type of rubber process oil.It is used in the manufacturing of natural as well as synthetic rubber products.It is synthesized from highly refined, solvent extracted base stocks of low sulphur content.It is used to achieve low milling temperature and shorter milling time. Hence,reduces power consumption.It helps to impart low heat buildup properties, and good air retention ability.Therefore used by most of the automotive tube manufacturing units.It is generally used in the compounding of rubber for procession of automotive compound particularly where butyl rubber is used. The oil used for compounding of rubber affects the final properties of goods manufactured.It improves the elongation strength and tear strength of the cured stocks. It also enhances ageing properties of the finished rubber goods.
