FEP Coated Polyimide Film (FH/FHF) – Heat-Sealable Composite Insulation
product detail
FEP Coated Polyimide Film (FH/FHF) – Heat-Sealable Composite Insulation
Product Overview
Our FEP Coated Polyimide Film (High-performance F46 PI Film) consists of a Polyimide film base coated on one side (FH) or both sides (FHF) with a layer of FEP (Fluorinated Ethylene Propylene). Unlike standard tapes, this material offers excellent heat-sealability, combining the high-temperature resistance of PI film with the superior moisture and chemical sealing of FEP.
This composite is the premier choice for wire wrapping and cable insulation in extreme environments, providing a permanent, hermetic seal after heat treatment.
Application
Industrial Applications & TDK Component Compatibility
-
TDK ALT Series & High-Frequency Transformers: Ideal for high-reliability winding in TDK ALT3232 and ALT4532 inductors where a moisture-proof, heat-sealed barrier is required for sensitive magnetic cores.
-
Magnet Wire Wrapping: Extensively used for wrapping copper and silver-plated conductors in high-performance motors and oil-filled transformers.
-
Aerospace & Military Electronics: Used in wire harnesses and flat cables for aircraft and satellites due to its low outgassing and high-temperature stability.
-
Flexible Printed Circuits (FPC): Acts as a high-grade coverlay or base material for flexible circuits requiring chemical inertness and thermal bonding.
-
Submersible Motor Winding: The fused FEP layer provides a perfect waterproof seal for motors operating in fluids or high-humidity conditions.
