Servo Rubbess 12 is a light-bodied, premium-grade rubber process oil specially formulated from carefully refined paraffinic and naphthenic base stocks of very low sulphur content. It is designed to serve as a processing aid and softener for a wide range of natural and synthetic rubber compounds. With its balanced solvency and viscosity characteristics, this product ensures easy blending, smooth processing and uniform dispersion of fillers and additives during compounding. Servo Rubbess 12 offers excellent compatibility with various elastomers such as SBR, PBR, NR and EPDM, helping to achieve improved flow, reduced mixing energy and enhanced finish quality of the final product. Owing to its lighter viscosity, it is particularly suited for the manufacture of soft rubber products requiring flexibility and surface smoothness, such as footwear components, mats, rubber sheets and molded goods. The oil’s low PCA (Polycyclic Aromatic Content) formulation meets global environmental and health regulations applicable to process oils used in rubber and polymer industries. The oil also helps lower milling and extrusion temperatures, minimizes blooming, and provides consistent plasticity control in rubber compounds. It enhances filler dispersion, reduces power consumption during mixing and promotes improved elongation and tensile properties in finished rubber articles. Servo Rubbess 12 also contributes to improved color stability, making it ideal for light-colored rubber goods and latex-based applications. With superior oxidation and thermal stability, Servo Rubbess 12 maintains its properties even under extended processing cycles. Its neutral odor, low volatility and controlled aniline point ensure optimal performance in both open-mill and internal-mixer operations. This makes it a reliable choice for rubber manufacturers seeking consistent quality, cleaner operation and compliance with modern process oil standards.
