Special Engineering Plastic Films
High-performance specialty thermoplastic films engineered for the most demanding industrial environments. This category covers DAFU's flagship advanced polymer film portfolio — including PEEK (Polyetheretherketone), PEI (Polyetherimide), PSU (Polysulfone), PPSU (Polyphenylsulfone), PPO, and PA12 (Nylon 12 / Polydodecanamide) films — with thickness ranges from ultra-thin 3μm up to 500μm and widths up to 1100mm, customizable roll diameter and length per customer specification.
These films deliver exceptional thermal stability (long-term service up to 170–250°C+ depending on grade), outstanding chemical resistance, superior electrical insulation, and dimensional stability. They are designed for critical applications across new energy vehicles, aerospace & aviation, 5G/high-speed communication, medical devices, unmanned systems, and high-end 3C electronics.
All products are manufactured under ISO9001 / ISO14001 certified systems, with full SGS / MSDS documentation support, and supplied globally to tier-1 supply chains (including Huawei, Samsung, vivo, OPPO, Lenovo, Midea, etc.).
