Servo Rubber 24 is a light-bodied, high-quality naphthenic-type process oil formulated specifically for the automotive tyre and tube manufacturing industry as well as for general applications in units producing various rubber goods. This ASTM Type 103 oil is designed to offer excellent compatibility with both natural and synthetic rubbers, including butyl rubber, ensuring superior processability and consistent product quality during rubber compounding operations. Servo Rubber 24 enhances the plasticity of rubber, allowing for smoother and easier mixing during the milling process, which in turn reduces milling time and power consumption. It helps accelerate the uniform dispersion of ingredients within the rubber matrix, improving the elongation, tensile strength, and tear resistance of the final compound. The oil’s unique formulation also contributes to better ageing properties of rubber products, extending their service life while maintaining flexibility and resilience. Its non-staining nature makes Servo Rubber 24 particularly suitable for the manufacture of white-walled automotive tyres and light-coloured rubber goods, where appearance and colour stability are critical. The oil’s low heat build-up and high rebound resilience enhance the dynamic properties of rubber, which is essential for tyres and other automotive components operating under continuous stress and varying temperatures. With a kinematic viscosity of 20–24 cSt at 40°C, flash point of 160°C, and pour point of 6°C, Servo Rubber 24 ensures stable performance and process efficiency in both hot and cold compounding environments. Its balanced composition also prevents unwanted staining or discolouration during storage and service life. Approved by leading manufacturers such as Madras Rubber Factory Ltd. (Mansfield Tyres) and Premier Tyres Ltd., Servo Rubber 24 is a trusted choice for rubber processing industries seeking consistent performance, improved processing characteristics, and superior end-product quality in tyre and moulded rubber manufacturing.
