Description

1-Chloroheptadecafluorooctane is a highly fluorinated chloroalkane, a key building block in advanced fluorochemical synthesis. This compound is valued for its exceptional chemical and thermal stability, as well as its unique hydrophobic and oleophobic properties derived from its perfluorinated chain. It is primarily sought after by manufacturers in the electronics, specialty polymers, and high-performance lubricants industries for creating materials with superior performance characteristics.

Application

• Fluoropolymer and Elastomer Synthesis: Serves as a critical monomer or intermediate in the production of specialized fluoropolymers (e.g., perfluoroalkoxy alkanes - PFA) and fluoroelastomers (FKM).
• Electronics Manufacturing: Used in the formulation of heat-transfer fluids for semiconductor manufacturing and as a precursor for dielectric fluids and specialty cleaning agents.
• High-Performance Lubricants and Greases: Acts as a base or additive for formulating lubricants that must perform under extreme temperatures and in chemically aggressive environments.
• Surface Treatment and Coatings: Employed to impart water, oil, and stain repellency to textiles, paper, and other substrates.
• Firefighting Foams (Legacy/Formulation R&D): Historically used in the development of aqueous film-forming foams (AFFF); relevant for research into alternative formulations.
• Chemical Synthesis Intermediate: A versatile starting material for synthesizing other perfluorinated compounds, surfactants, and pharmaceuticals.
