Features Of Sanyo Chemical POLYMIDE L Polyimide Thermal Storage Surfactant

  1. Enhances thermal stability and phase-change efficiency in latent heat storage systems.

  2. Improves dispersion and interfacial compatibility of polyimide-based PCM (Phase Change Material) composites.

  3. Reduces surface tension without compromising high-temperature performance (>250 °C).

  4. Enables uniform microencapsulation of PCMs for improved cycling durability and thermal reliability.

  5. Compatible with aromatic polyimide precursors and solvent-based processing routes (e.g., NMP, DMAC).

Typical Applications Of Sanyo Chemical POLYMIDE L Polyimide Thermal Storage Surfactant

  1. Thermal management layers in aerospace composite structures.

  2. High-performance PCM additives for electric vehicle battery thermal regulation systems.

  3. Stabilizer for polyimide-PCM nanocomposites used in smart building envelope materials.

  4. Interfacial modifier in flexible printed circuit board (FPCB) heat-dissipating films.

  5. Functional additive in high-temperature thermal interface materials (TIMs) for power electronics.
