Description

Hfpo Oligomer Acid Fluorides CAS NO 65208-35-7 are a specialized class of perfluoropolyether (PFPE) derivatives, serving as key reactive intermediates in advanced fluoropolymer synthesis. Their value lies in the introduction of perfluorinated oligomeric chains, imparting exceptional chemical resistance, thermal stability, and low surface energy to final materials. This product is essential for R&D and production teams in the specialty polymers, high-performance lubricants, and surface modification sectors seeking to engineer materials with superior performance characteristics.

Application

• Fluoropolymer Modification: As a macromonomer or chain extender for synthesizing high-performance fluorinated elastomers and thermoplastics with enhanced oil and chemical resistance.
• Surface Treatment Agents: Used to create durable, hydrophobic, and oleophobic coatings for textiles, electronics, and optical components.
• Specialty Lubricants & Greases: A key precursor for formulating perfluoropolyether (PFPE)-based lubricants that are stable in extreme environments (high vacuum, oxidative, corrosive).
• Pharmaceutical & Agrochemical Intermediates: Enables the synthesis of fluorinated bioactive molecules by introducing stable perfluorinated segments.
• Adhesive & Sealant Formulations: Imparts water and solvent repellency, as well as improved weatherability, to high-end sealants and adhesives.
• Advanced Material Research: Serves as a building block in academic and industrial R&D for developing novel fluorinated nanomaterials and composites.

Quality Control

Our Hfpo Oligomer Acid Fluorides are produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including FT-IR and NMR spectroscopy for structural confirmation and titrimetric methods for functional group assay. We ensure consistency in oligomer distribution and acid fluoride content. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with every shipment to guarantee compliance with your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; ensure containers are sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity. Keep away from heat, open flames, and incompatible materials.
