Uses & manufacturing
Uses
The higher olefins are used primarily as chemical intermediates; C18-C20 olefins are used in drilling fluids for off-shore oil exploration; C20-C24 olefins are used in wax applications (i.e., candles, board and box coatings, and polishes), in metal working fluids, and as intermediates for lube oil additives, epoxides (for epoxy resins and polyurethanes), chlorinated plasticizers for PVC, and fire retardant agents; [EPA ChAMP]
