Polyetheretherketone Film

Introduction
Polyetheretherketone (PEEK) film is a high-performance thermoplastic polymer film known for its exceptional mechanical strength, thermal stability, and chemical resistance. It is widely used in demanding industrial and high-tech applications due to its reliability and versatility under extreme conditions.

Key Properties

1. High Thermal Stability

   • Continuous service temperature up to 250°C; short-term tolerance exceeding 300°C.

   • Low coefficient of thermal expansion (CTE), ensuring dimensional stability in variable temperatures.

2. Excellent Mechanical Performance

   • High tensile strength, stiffness, and fatigue resistance.

   • Maintains properties across a broad temperature range.

3. Outstanding Chemical Resistance

   • Resists acids, bases, organic solvents, oils, and hydrolysis.

   • Suitable for harsh chemical environments.

4. Electrical Properties

   • Good electrical insulation even at high temperatures and humidity.

   • Low dielectric constant and dissipation factor.

5. Flame Resistance and Low Smoke Emission

   • Complies with UL 94 V-0 flammability standards.

   • Minimal toxic gas and smoke emission when exposed to fire.

6. Lightweight and Processable

   • Can be thermoformed, laminated, and metallized for integration into complex assemblies.
     

     Application Scenarios

   • Aerospace
     Used as insulation films for wiring, lightweight composite interlayers, and thermal barriers in aircraft and spacecraft components.

   • Electronics and Electrical
     Applied in flexible printed circuits (FPCs), motor insulation, and high-temperature capacitor films due to its stable dielectric properties.

   • Industrial Manufacturing
     Serves as release films, barrier layers, and lining materials in high-temperature molding processes (e.g., composite autoclave curing).
