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
Applications
- Electrical insulation tape, spacers, and liners
- Wire harness and coil wrapping
- High-frequency circuit board laminates
- Transformer and motor insulation
- High-temperature masking in powder coating and electroplating
