FEP High Temperature Film – Transparent Fluoropolymer Film

Premium FEP high temperature film with excellent heat resistance, non-stick surface, chemical resistance and electrical insulation.

Custom thickness FEP film for composite molding, electronics, aerospace and industrial release applications.

Product Overview

FEP High Temperature Film is a high-performance thermoplastic fluoropolymer film manufactured from pure fluorinated ethylene propylene resin. As an upgraded fluoroplastic material, FEP film combines the excellent properties of PTFE with superior thermoplastic processability, making it one of the most versatile high-temperature films for modern industrial manufacturing.

This transparent FEP film features outstanding high temperature resistance, extreme chemical inertness, smooth non-stick surface, stable electrical insulation and excellent outdoor weather resistance. It remains consistent in physical and mechanical performance under continuous high-temperature working conditions, harsh chemical environments and long-term outdoor exposure.

Widely used as mold release film, electrical insulation film, corrosion-resistant barrier and protective film in composite manufacturing, electronics, aerospace, medical and chemical industries, our FEP high temperature film provides reliable high-temperature solution for precision industrial production.

Key Features & Performance Advantages

Excellent High Temperature Resistance Our FEP high temperature film supports continuous working temperature from -200°C to 205°C, with intermittent peak temperature up to 260°C. No deformation, shrinkage, cracking or performance attenuation occurs during long-term high-temperature cycling, ensuring stable operation in high-heat production environments.

Superior Non-Stick & Smooth Surface FEP film owns ultra-low surface energy and excellent demolding performance. Resins, adhesives, prepreg materials and composite products can be easily separated from the film surface without residue, effectively improving product surface finish and reducing production defects.

Outstanding Chemical Resistance Completely resistant to most strong acids, strong alkalis, organic solvents, oils and corrosive liquids. The film maintains stable performance in various harsh chemical working conditions and provides effective anti-corrosion isolation protection.

Stable Electrical Insulation Property With low dielectric constant, low dielectric loss and high dielectric strength, FEP high temperature film provides reliable insulation protection in high-frequency and high-temperature electronic environments. Its insulation performance is hardly affected by temperature and frequency changes.

High Transparency & Weather Resistance Natural transparent appearance with high light transmittance. The film resists UV radiation, aging and yellowing, suitable for long-term outdoor and optical protection scenarios.

Thermoplastic Processable & Customizable Different from PTFE film, FEP film can be heat sealed, thermoformed, laminated and welded. Surface etching and plasma treatment are available to enhance bonding and adhesion performance for composite lamination applications.
