PTFE Cable Insulation Film

 

PTFE Cable Insulation Film is a high-performance electrical insulation material manufactured from 100% virgin polytetrafluoroethylene (PTFE). It is widely used in wire and cable insulation, wrapping, and separation layers, especially in applications requiring high dielectric strength, extreme temperature resistance, and long-term reliability.

Thanks to PTFE's exceptional electrical and chemical properties, this insulation film provides stable performance in harsh environments, making it an ideal choice for power cables, high-voltage cables, communication cables, aerospace wiring, and industrial electrical systems.

Key Advantages of PTFE Cable Insulation Film

1. Excellent Electrical Insulation Performance

Very high dielectric strength

Low dielectric constant and dissipation factor

Stable insulation properties across a wide frequency range

Suitable for high-voltage and high-frequency cable applications

2. Outstanding Temperature Resistance

Continuous working temperature: –260°C to +260°C

Maintains insulation performance under extreme heat or cold

Ideal for cables exposed to thermal cycling or high operating temperatures

3. Superior Chemical & Environmental Resistance

Resistant to oils, fuels, solvents, acids, alkalis, and moisture

Non-aging, non-oxidizing, and UV resistant

Suitable for outdoor and aggressive industrial environments

4. Thin, Lightweight & Flexible

Enables compact cable design

Easy to wrap or laminate onto conductors

Maintains flexibility without cracking or embrittlement

5. Long Service Life & High Reliability

Does not harden or degrade over time

Low friction surface reduces damage during cable installation

Excellent consistency for mass production
