  • Applications

    2-Hexadecene (CAS 26741-29-7) is a long-chain internal olefin primarily used as an industrial chemical intermediate. In the plastics/polymer sector, it can be used as a comonomer or feedstock for the synthesis of polyolefins to tailor material properties. In coatings, inks, and adhesives, it may serve as a processing aid or additive to adjust rheology and formulation compatibility. It can also be used as a component in lubricant formulations or as a lubricity additive to improve wear performance. Final applications depend on local regulations and formulation constraints.
