Description

3,5,7,9,11-Pentaoxatridecafluorododecanoic Acid is a high-purity, fluorinated organic acid characterized by its unique perfluoropolyether (PFPE) chain terminated with a carboxylic acid group. This structure provides exceptional chemical and thermal stability, low surface energy, and hydrophobic/oleophobic properties, making it a valuable intermediate for advanced material synthesis. It is primarily utilized in the development of specialty polymers, high-performance lubricants, and sophisticated surface coatings where extreme environmental resistance is required.

Application

• Fluorinated Polymer Synthesis: A key monomer for producing high-performance fluoropolymers and perfluoropolyethers (PFPEs) with enhanced chemical resistance and thermal stability.
• Specialty Lubricants & Greases: Used in formulating advanced lubricants for extreme environments, including aerospace, vacuum systems, and aggressive chemical processing.
• Surface Modification Agents: Imparts durable water, oil, and stain repellency to textiles, membranes, and electronic components.
• Pharmaceutical & Agro-chemical Intermediates: Serves as a building block for introducing fluorinated segments into active molecules to modify their bioavailability and metabolic stability.
• Advanced Coating Formulations: Incorporated into coatings for medical devices, optical fibers, and corrosion protection where low friction and non-stick properties are critical.
• Electronics Industry: Potential use in the formulation of dielectric fluids and heat transfer fluids for sensitive electronic systems.
