Application
1. Acts as a key monomer for synthesizing heat-resistant polyimide resins used in high-performance electronic and aerospace materials.
2. Serves Cyclobutane-1 2 3 4-tetracarboxylic dianhydride as a cross-linking agent for modifying epoxy resins to enhance their thermal stability and mechanical strength.
3. Functions as a building block in the synthesis of specialty polymers with excellent chemical resistance and dielectric properties.
Storage and Precautions
Cyclobutane-1 2 3 4-tetracarboxylic dianhydride should be stored in a tightly sealed container at 15–25°C, in a cool, dry, and well-ventilated area away from direct sunlight. It is sensitive to moisture, so keep it far from humid environments to prevent hydrolysis and 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.
