FEP Coated Kapton Polyimide Tape

FEP Coated Kapton is a high-performance composite film produced by made by polyimide film with one side or double side FEP coated(Fluorinated Ethylene Propylene). When combined with FEP resin, the Polyimide film remains excellent heat and electrical properties. This engineered combination creates a material that synergizes the best properties of both polymers.

Standard Constructions:

Single-Side Coated: FEP layer / Polyimide base film

Double-Side Coated: FEP layer / Polyimide base film / FEP layer

Advantages of FEP Coated Kapton Film:

1. Superior Chemical Barrier: FEP layer provides complete protection against most industrial chemicals

2. Excellent Release Properties: Non-stick surface with very low surface energy (18-22 dynes/cm)

3. Hermetic Sealing Capability: Can be heat-sealed to create impervious enclosures

4. Wide Temperature Range: Maintains properties from cryogenic to 200°C continuous

5. Electrical Integrity: Combined dielectric strength exceeds either material alone

6. Regulatory Compliance: Typically complies with FDA, USP Class VI, RoHS, REACH, and UL standards

Widely used in the electronics and electrical industries, such as lithium battery insulation and packaging, high-frequency special capacitors, thermoplastic composite material processing, aerospace and military fields, etc.
