Applications in polyimide and electronic materials, etc.
Polyimide raw materials: Used in the manufacture of high-temperature-resistant films, insulating varnishes, and engineering plastics to meet the packaging needs of electronic devices.
Epoxy resin curing matting agents: Improve the heat resistance and mechanical strength of coatings suitable for aerospace and electronic substrates.
Polyester and polyether: PMDA is used in synthetic polymers, specialty coatings and composites
Battery Materials: As a stabilizing component of positive active materials for lithium-ion and sodium-ion batteries
Why PMDA Is Essential for High-Performance Polymers?
- Functional properties: As a key monomer in the synthesis of polyimide, pyromellitic anhydride (PMDA) gives the material high
thermal stability (decomposition temperature exceeds 500°C), high mechanical strength (tensile strength reaches 170-400MPa) and excellent chemical resistance through a rigid aromatic ring structure.
- Typical products: Polyimide film: used as a base material for flexible circuit boards and high-temperature-resistant motor insulation materials. It is known as the "golden film".
- Engineering plastics: manufacturing aerospace components and electronic packaging materials, maintaining performance above 380°C.
- Industry cases: International brands such as DuPont Kapton film and Japan's Upilex series all use PMDA as raw materials.
It is also widely used by international manufacturers in the fields of electronics and high-performance materials.
