Description

Ethanesulfonic Acid,1,1,2,2-Tetrafluoro-2-[1,2,2-Trifluoro-2-[(Trifluoroethenyl) Oxy]-1-(Trifluomethyl)Ethoxyl]-,Sodium Salt, Polymer With Tetrafluoroethene is a specialized fluorinated polymer salt, representing a high-performance material engineered for demanding chemical environments. This compound is valued for its unique combination of chemical resistance, thermal stability, and ionic properties derived from its perfluorinated backbone and sulfonate functionality. It is primarily sought by advanced material scientists and process engineers in the fluoropolymer modification, specialty coatings, and electrochemical membrane sectors.

Application

• Ion-Exchange Membranes: A key component in the formulation of perfluorinated sulfonic acid (PFSA) type membranes, such as those used in chlor-alkali processes and fuel cells.
• Fluoropolymer Additive: Acts as a functional comonomer or additive to enhance the surface properties, adhesion, or conductivity of polytetrafluoroethylene (PTFE) and related fluoropolymers.
• Specialty Coatings: Used to create chemically inert, non-stick, and thermally stable coatings with specific surface energy characteristics for industrial equipment.
• Electrochemical Sensors: Serves as a selective layer or membrane component in sensors requiring high chemical resistance and ionic conductivity.
• Catalyst Support Systems: Utilized in the development of supported catalyst systems where an inert, high-surface-area fluorinated matrix is required.
• Advanced Composite Materials: Incorporated into high-performance composites to impart fluoropolymer-like properties such as extreme hydrophobicity and low friction.

Quality Control

Our production of this high-value fluorinated polymer adheres to stringent quality management systems. Each batch is characterized using advanced analytical techniques including NMR, FT-IR, and GPC/SEC to confirm polymer structure, molecular weight distribution, and ionic capacity. Certificates of Analysis (COA) detailing lot-specific data are provided and traceability is maintained throughout the supply chain. We ensure compliance with relevant industrial standards and can support customer-specific validation requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place. Recommended storage temperature is between 15°C and 25°C. The container should be kept tightly sealed in a desiccated environment to prevent moisture uptake, which can affect material properties. Keep away from strong acids and strong oxidizing agents.
