Medium Oil 45/55

Whatsapp Order

Medium Oil 45/55 is a petroleum-derived mineral oil that falls within the mid-range viscosity category, typically comprising a blend of 45% light and 55% heavy paraffinic fractions. Known for its excellent solvency, thermal stability, and lubrication properties, Medium Oil is widely used in rubber processing, industrial applications, and chemical blending. It appears as a clear to pale amber liquid with a neutral odor, and it demonstrates good compatibility with various elastomers and polymers. This oil enhances the flexibility, softness, and processing efficiency of rubber compounds while maintaining stability under heat and mechanical stress.

Supplied in 180 kg industrial-grade drums, Medium Oil (45/55) is ideal for large-scale use in manufacturing and processing environments.
