Description

Perfluoropolyether Diacyl Fluoride (N=2) 98 is a high-purity, reactive perfluorinated intermediate characterized by its terminal acyl fluoride groups. This compound is critical for introducing perfluoropolyether (PFPE) segments into advanced materials, imparting exceptional chemical inertness, thermal stability, and low surface energy. It is essential for R&D and production in industries requiring high-performance fluorinated polymers and surface modifiers, such as specialty lubricants, advanced coatings, and functional materials for demanding environments.

Application

• Synthesis of PFPE-based Lubricants & Greases: Serves as a key monomer for creating high-performance, thermally stable, and chemically resistant lubricants for aerospace, vacuum, and semiconductor manufacturing equipment.
• Production of Fluorinated Surfactants & Additives: Used to manufacture surfactants and surface-active agents that provide superior wetting and leveling in demanding coating formulations.
• Advanced Polymer Modification: Acts as a reactive intermediate for grafting PFPE chains onto polymers to enhance their hydrophobicity, oleophobicity, and chemical resistance for protective coatings and membranes.
• Functional Fluids for Electronics: A precursor for fluids used in heat transfer and dielectric applications within sensitive electronic systems due to PFPE's excellent insulating properties.
• Surface Treatment Agent: Used to create low-friction, non-stick, and easy-clean surfaces on metals, ceramics, and plastics.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of fluorinated building blocks for active ingredients that require enhanced metabolic stability and bioavailability.

Quality Control

Our Perfluoropolyether Diacyl Fluoride (N=2) 98 is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including NMR (19F, 1H), FT-IR, and titration methods. We provide full traceability and Certificates of Analysis (COA) with each shipment, detailing purity, identity, and key impurity profiles to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and reacts with fluoride/strong alkali. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture uptake and decomposition. Isolate from incompatible materials.
