Servo Rubber EF-5 is a high-quality Residual Aromatic Extract (RAE) type rubber process oil formulated to deliver exceptional processing performance in both natural and synthetic rubber compounds. Developed with superior-quality aromatic base oils, Servo Rubber EF-5 offers an optimum balance of solvency, stability, and environmental compliance, making it ideal for advanced rubber compounding applications. The product is refined to a carefully controlled aromatic content, ensuring excellent compatibility with a wide range of rubber polymers such as SBR, NR, and PBR, while maintaining a low level of polycyclic aromatic hydrocarbons (PAH) to comply with stringent environmental standards. Its outstanding solvency characteristics enhance the uniform dispersion of carbon black and other fillers, improving the plasticity, flexibility, and workability of rubber compounds. Servo Rubber EF-5 significantly reduces energy consumption during mixing and extrusion by providing superior lubrication and lower friction at processing interfaces, ensuring smoother operations and reduced mechanical strain on equipment. It also enhances extrusion finish, improves the surface smoothness of molded rubber products, and ensures dimensional stability in final goods. With excellent oxidation resistance and thermal stability, the oil maintains its properties even at elevated temperatures, offering consistent performance across varying industrial conditions. Servo Rubber EF-5 is recommended for use in the tyre, conveyor belt, footwear, and molded rubber goods industries, where high solvency, improved filler distribution, and long-term process reliability are essential. Engineered for modern rubber manufacturing setups, Servo Rubber EF-5 ensures better process efficiency, improved end-product quality, and superior cost-effectiveness, making it a trusted choice for manufacturers seeking high-performance, environmentally responsible rubber processing oil.
