Dafu

Struggling to find an engineering plastic film that survives extreme heat while maintaining flawless electrical insulation? Meet DAFU PPO Film—the high-performance solution engineered for the next generation of electronics.

Unlike standard polycarbonate films, our Polyphenylene Oxide (PPO) film​ delivers a rare combination of 182°C heat deflection​ and ultra-low dielectric loss, making it the gold standard for high-frequency communication devices and precision motors.

Target Applications

DAFU PPO Film excels where standard films fail:

1. 5G Communication & High-Frequency Devices:​ Low dielectric constant minimizes signal loss in base stations and antennas.
2. Automotive & EV Systems:​ High heat resistance for sensors, battery insulation, and motor slot liners.
3. Precision Motors:​ Used as phase insulation paper and slot insulation due to high rigidity and heat resistance.
4. Aerospace & Defense:​ Reliable performance in extreme thermal cycling environments.
5. High-End Consumer Electronics:​ Internal insulation for high-wattage fast-charging adapters and laptops.
