Description

4,4'-Oxybisbenzoic Acid Polymer With 4,4'-[2,2,2-Trifluoro-1-(Trifluoromethyl)Ethylidene]Bis[2-Aminophenol] is a high-performance fluorinated poly(arylene ether ketone)-type thermoplastic polymer engineered for extreme thermal stability and chemical resistance. It delivers exceptional dielectric properties, low moisture absorption, and outstanding dimensional stability under prolonged thermal stress — making it critical for mission-critical advanced material systems. This polymer is primarily sought by manufacturers of high-reliability aerospace composites, semiconductor processing components, and next-generation flexible printed circuit substrates requiring continuous operation above 250 °C.

Application

• Aerospace: Structural components and insulation films in jet engine nacelles and avionics housings
• Semiconductor manufacturing: Wafer handling fixtures, plasma etch chamber liners, and electrostatic chucks
• Flexible electronics: High-temperature stable base films for polyimide-free flexible printed circuits (FPCs)
• Medical device sterilization: Reusable trays and instrument carriers compatible with steam, EtO, and gamma sterilization cycles
• Oil & gas downhole sensors: Encapsulation matrix for pressure/temperature transducers operating at >200 °C and 15,000 psi
• Advanced filtration: Membrane support layers for aggressive solvent-based nanofiltration in pharmaceutical purification

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 meet REACH Annex XVII compliance requirements. Testing includes full spectral verification (FTIR, 19F NMR), residual monomer quantification (GC-MS), and thermal performance validation (TGA/DSC per ASTM D3850 and D3418).

Storage

Preserve in a tightly closed container, protected from light. Store at 15–25 °C in a dry, well-ventilated area. Avoid exposure to strong alkalis and organic solvents. Keep away from sources of ignition and incompatible materials including oxidizing agents.
