    Hexafluoroisopropylidene Diphthalic Anhydride CAS 1107-00-2

    Hexafluoroisopropylidene Diphthalic Anhydride is a fluorinated aromatic dianhydride used as a chemical raw material in high‑performance polymer systems, commonly referred to as 6FDA, hexafluoroisopropylidene diphthalic anhydride, or fluorinated dianhydride in technical documentation. Identified by CAS 1107‑00‑2, its rigid aromatic backbone combined with a hexafluoroisopropylidene linkage influences chain spacing and thermal behavior during polycondensation reactions. It is typically applied as a polyimide monomer in industrial polymer synthesis processes where controlled molecular architecture is required. From a supply perspective, the material is provided with competitive factory pricing, customized specifications, and full documentation including MSDS, TDS, COA, suitable for regulated bulk supply for industrial use.

    Applications

    Flexible Displays & Optics

    • Colorless Polyimide (CPI): The primary monomer for producing transparent, heat-resistant films used as cover windows in foldable smartphones and flexible OLED displays.
    • Optical Films: Used in optical waveguides and anti-reflective coatings due to its low refractive index and high transparency.

    Microelectronics

    • Insulating Layers: Used to produce low-k dielectric interlayers in integrated circuits (ICs) to reduce signal delay and power consumption.
    • Photoresists: Acts as a precursor for photosensitive polyimides (PSPI) in lithographic processes.

    Membrane Technology

    • Gas Separation: 6FDA-based polyimides exhibit high permeability and selectivity, making them ideal for gas separation membranes (e.g., $CO_2/CH_4$ separation) in natural gas processing.

    Quality Assurance (QA/QC)

    Our 6FDA is manufactured in a dust-free, controlled environment to meet the rigorous standards of the semiconductor and display industries.

    • Purity Control: We utilize HPLC to ensure a minimum purity of 99.5% and ICP-MS to strictly control trace metal ions (Fe, Na, K < 5 ppm), which is critical for electronic performance.
    • Purification: Multiple recrystallization steps are employed to remove organic impurities and minimize free acid content.
    • Packaging: Vacuum-sealed in double-layer PE bags inside fiber drums to prevent moisture absorption and contamination.

    Storage & Safety

    Storage Guidelines

    • Moisture Sensitivity: Anhydrides are highly sensitive to moisture and will hydrolyze to the corresponding acid. Store in a tightly sealed container in a dry environment (desiccated storage recommended).
    • Temperature: Store in a cool place (below 25°C), away from direct sunlight and heat sources.
    • Inert Atmosphere: Recommended to store under nitrogen to maintain shelf-life stability.

    Safety & PPE Recommendations

    • Handling: Perform operations in a fume hood to avoid dust inhalation.
    • PPE: Wear particulate respirators (N95/P2), chemical-resistant gloves, and safety goggles.
    • First Aid: If inhaled, move to fresh air. If on skin, wash with soap and water. If in eyes, rinse cautiously for 15 minutes.

    FAQ - Technical & Supply Chain

    • Q:

      Is 6FDA supplied as a polymer or as a monomer raw material?

      A: It is supplied as a monomer raw material intended for polymer synthesis rather than as a finished polymer product.
    • Q:

      What is the typical functional role of 6FDA in polymer synthesis?

      A: It is typically used as a dianhydride component in polycondensation systems to build polymer backbones with defined structural characteristics.
