Application
1. Acts as a core monomer for synthesizing fluorene-containing polyimide resins with exceptional thermal stability and mechanical toughness.
2. Applied 9 9-Bis(3 4-dicarboxyphenyl)fluorene Dianhydride in manufacturing high-performance optoelectronic materials like LCD alignment films and high-temperature resistant insulation layers.
3. Utilized as a building block for producing aerospace-grade composite materials with excellent dielectric properties and chemical resistance.
Storage and Precautions
9 9-Bis(3 4-dicarboxyphenyl)fluorene Dianhydride should be stored in a tightly sealed, moisture-proof container at 15–25°C, in a cool, dry and well-ventilated area away from direct sunlight. It is prone to hydrolysis when exposed to moisture, so keep it isolated from water, humid environments, strong acids and bases to prevent quality deterioration.
During handling, wear chemical-resistant gloves, goggles and a lab coat, and operate in a fume hood to avoid dust inhalation and skin/eye contact. Reseal the container immediately after use. Dispose of waste strictly following local hazardous chemical regulations.
