Description

Perfluorooctadecanoic Acid CAS NO 16517-11-6 is a long-chain perfluorinated carboxylic acid (PFCA) characterized by its high chemical and thermal stability due to the strong carbon-fluorine bonds. This compound is valued for its exceptional hydrophobic and oleophobic properties, making it a key functional intermediate in advanced material science. It is primarily utilized by industries focused on developing high-performance surface treatments, specialty polymers, and fluorochemical synthesis.

Application

• Surface Modifier and Coating Agent: Imparts water, oil, and stain repellency to textiles, leather, paper, and non-woven fabrics.
• Fluoropolymer Synthesis: Serves as a monomer or building block for creating specialized fluoropolymers with enhanced chemical resistance and low surface energy.
• Lithography and Semiconductor Processing: Used in the formulation of photoresists and anti-reflective coatings for advanced microelectronics fabrication.
• Fire-Fighting Foams (Historical/Research): As a component in the research and development of aqueous film-forming foams (AFFF) for liquid fuel fires.
• Chemical Intermediate: A precursor for synthesizing fluorinated surfactants, emulsifiers, and other derivatives with tailored properties.
• Material Science Research: Employed in academic and industrial R&D to study the behavior of perfluorinated compounds and develop novel nanomaterials.
