Description
1-Octadecene (CAS 112-88-9) is a straight-chain alpha-olefin with the molecular formula C18H36, commercially available under trade names including Neodene 18, Gulftene 18, Dialen 18, and NSC 66460. It carries no assigned E-code and is classified under HS code 29012990.
In polyolefin production, 1-octadecene acts as a comonomer with ethylene or propylene, where its long carbon chain modifies polymer density and flexibility at the molecular level. In lubricant formulation, it serves as a base fluid precursor or synthetic base stock intermediate, contributing to viscosity profile and thermal stability in metalworking and industrial lubricant applications.
1-Octadecene is supplied as a liquid and is available in technical and high-purity grades to meet different formulation requirements. The substance is registered under REACH and must be handled in accordance with applicable EU chemical regulations. Packaging formats typically include drums and intermediate bulk containers for industrial procurement.
