Product Description

PTFE tape delivers reliable electrical insulation at temperatures where conventional materials break down. Two forms are available: glass-fiber-reinforced PTFE tape for combined insulation and mechanical strength, and pure PTFE film tape for superior conformability and dielectric performance.

Glass-Fiber-Reinforced PTFE Tape

Woven glass fiber cloth coated with PTFE and backed with high-temperature silicone adhesive. Combines electrical insulation with the tensile strength needed for wrapping coils, wire harnesses, and equipment components.

Thickness	Adhesion (N/25 mm)	Tensile Strength (N/25 mm)	Max Width	Temp Range
0.13 mm	≥ 150	≥ 205	1250 mm	−70 to 260 °C
0.18 mm	≥ 240	≥ 300	1250 mm	−70 to 260 °C
0.25 mm	≥ 350	≥ 405	1250 mm	−70 to 260 °C

Slit to any width from 7 mm to 600 mm.

Pure PTFE Film Tape

Non-reinforced PTFE film for applications that demand tight conformability, high dielectric strength, or anti-static properties. Standard widths from 13 mm to 100 mm.

Key Properties

High dielectric strength — suitable for high-frequency laminates and copper-clad laminate (CCL) production
Operating range: −70 °C to 260 °C with long-term thermal stability
Chemically inert — unaffected by strong acids, alkalis, and organic solvents
Dimensionally stable — elongation at break below 5 %
Flex-fatigue resistant — wraps cleanly around small-diameter components
Self-extinguishing and flame retardant
