Description

Alkenes, C18-24 Alpha, Dimers is a high-purity, defined mixture of long-chain α-olefin dimers. This product is valued for its excellent chemical stability and hydrophobic properties, making it a versatile intermediate and functional fluid component. It is primarily sought by manufacturers in the lubricant, polymer, and specialty chemical industries for applications requiring high-performance olefinic feedstocks.

Application

• Synthetic Lubricant Base Stocks: Used as a high-viscosity index (VI) component in the formulation of premium synthetic lubricants and hydraulic fluids.
• Polymer & Resin Modifiers: Acts as a co-monomer or plasticizer in the production of polyethylene, polyalphaolefins (PAO), and other specialty polymers to enhance flexibility and processing.
• Chemical Intermediate: Serves as a key feedstock for further chemical reactions, including hydrogenation, sulfonation, and epoxidation, to produce surfactants, corrosion inhibitors, and other derivatives.
• Personal Care & Cosmetics: Employed as an emollient and skin-conditioning agent in high-end cosmetic formulations, providing a non-greasy feel.
• Adhesives & Sealants: Functions as a tackifier and viscosity modifier in hot-melt and pressure-sensitive adhesive systems.
• Metalworking Fluids: Incorporated as a lubricity additive and carrier fluid in cutting, grinding, and drawing oils.
