ODPA CAS 1823-59-2: Comprehensive Product Guide & User Insights

1. Product Overview & Specifications

ODPA (4,4′-Oxydiphthalic Anhydride), CAS 1823-59-2, is a high-purity aromatic dianhydride monomer critical for manufacturing advanced polyimide polymers. Its unique molecular structure enables exceptional thermal stability and mechanical performance in extreme environments.

2. Key Applications & Use Cases

2.1 High-Temperature Polyimide Films

ODPA-based films maintain structural integrity at 300-400°C, ideal for aerospace engine components and electric vehicle battery insulation.

2.2 Microelectronic Encapsulation

Ultra-low CTE (8-12 ppm/°C) prevents delamination in semiconductor packaging under thermal cycling conditions.

2.3 Composite Matrices

Enables carbon fiber-reinforced composites with 25% higher flexural strength than BTDA-based systems.

3. Performance Comparison with Alternatives

4. Industry Implementation Examples

4.1 Flexible Printed Circuits

Major Asian PCB manufacturer achieved 40μm-thick flexible circuits with 15% improved folding endurance using ODPA-based polyimides.

4.2 Satellite Components
