Description

4-(4-Hydroxyphenyl)-1(2H)-Phthalazinone Polymer With Bis(4-Fluorophenyl)Methanone is a high-performance fluorinated aromatic polymeric intermediate engineered for advanced functional materials. It delivers exceptional thermal stability, chemical resistance, and dielectric properties—critical for next-generation electronic and aerospace applications. This specialty polymer is primarily utilized by R&D laboratories and industrial manufacturers developing high-end polyimide analogues, thermally stable coatings, and fluorinated engineering resins. Its unique biphenyl–phthalazinone–fluoroketone architecture enables precise control over chain rigidity and intermolecular interactions.

Application

• High-temperature polymeric matrix resins for aerospace composite laminates
• Dielectric layers in flexible printed circuit boards (FPCBs) requiring low moisture absorption and high Tg
• Charge-transport layers in organic light-emitting diodes (OLEDs) and perovskite solar cells
• Thermally stable binder resins for ceramic green tape processing and low-temperature co-fired ceramics (LTCC)
• Functional additive in fluorinated polyamide-imide blends to enhance solvent resistance and dimensional stability
• Building block for synthesizing high-performance anion-exchange membranes (AEMs) in fuel cell applications
• Photoresist component in advanced semiconductor lithography (EUV-compatible formulations under development)
• Matrix material for radiation-shielding polymer composites in nuclear instrumentation housings

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches conform to ISO 9001:2015 certified manufacturing protocols and are evaluated against stringent internal specifications—including assay (≥99.5% by HPLC), residual monomer content (<0.1%), heavy metals (<5 ppm), and moisture content (<0.2% by Karl Fischer). Testing follows ASTM D6988 and ISO 1628-4 methodologies where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store at 15–25°C in a dry, well-ventilated area. Due to its fluoride/strong alkali sensitivity, avoid contact with basic solutions or fluorinating agents. Keep away from moisture sources and maintain relative humidity below 40%.
