  • Applications

    2-Methylhexadecane is a long-chain branched paraffin commonly used as a non-polar solvent or diluent in industrial formulations such as coatings, inks, and cleaning agents. It also serves as a base oil or component in mineral-oil–based lubricants and greases, and can function as a lubricant or processing aid in plastic and polymer processing to reduce friction during extrusion and molding. Additionally, due to its paraffinic nature with a high boiling point and low volatility, it is encountered as a component in mineral oil stocks for industrial formulations and can participate as a processing solvent in various formulations.
