ptfe insulation

PTFE materials are often specified for their resistance performance properties against fire, smoke, oil and chemical solvents. It offers superior thermal stability, with a wide operating temperature range between -200°C and +260°C, and also provides good resistance to water, making it suitable for hot and wet environments.

Why is PTFE a good insulator?

High dielectric strength

Low dissipation factor

Unaffected by exposure to moisture, humidity, and liquid

Very high operating temperatures

ptfe insulation are not subject to creeping or deformity over time

Provides resistance to UV radiation, stress, mold, and chemicals
