Unsintered polytetrafluoroethylene (PTFE) tape
Product Introduction 
Unsintered PTFE tapes are specially designed for high-frequency, high-power communication cables and high-temperature wires. They feature excellent dimensional stability and uniform electrical, mechanical, and thermal properties. Their superior electrical performance, fire resistance, low friction, high flexibility, and excellent weather and chemical resistance provide comprehensive and efficient protection for various wires and cables.
Product Properties:
Low thermal shrinkage (<10%);
Excellent high-temperature performance;
Low dielectric constant, high dielectric strength;
Low coefficient of friction, high flexibility;
High tensile strength and quick rebound capability;
Application Areas:
Microwave coaxial cables;
High-frequency data cables;
Low-loss phase-stable cables;
High-temperature wires;
