PTFE film adhesive tape combines the inherent properties of PTFE – high temperature resistance, low friction, non‑stick, and chemical inertness – with a pressure‑sensitive adhesive (silicone or acrylic). This makes it an indispensable material across many industries.
- Heat Sealing & Packaging
· Sealing bars & jaws: Used as a cover layer on heat‑sealing equipment (e.g., continuous band sealers, impulse sealers) to prevent molten plastic films (PE, PP, PET) from sticking to the hot metal surfaces.
· Heat‑shrink tunnels: Protects guide rails and conveyor parts from adhesive build‑up.
· Release liner: Prevents glue or resin from adhering to machinery during production.
- Electronics & Electrical Industry
· Insulation & protection: Provides dielectric insulation for coils, transformers, capacitors, and wire harnesses due to its high dielectric strength and thermal stability (up to 260 °C continuously).
· PCB manufacturing: Used as a masking tape during soldering or wave soldering to protect sensitive components, as it withstands high temperatures without leaving residue.
· Flat cable binding: Offers a smooth, low‑friction surface for flex circuits and ribbon cables.
