PTFE Sodium-Etched Film On One Side (or two side), PTFE Etching Sheet

PTFE Film and PTFE Sheets are available in multiple thicknesses with single- or double-sided etching in roll form or cut to size sheets. 

The chemical etching process enhances adhesion, enabling PTFE films to bond effectively with transfer adhesives, epoxies, or liquid adhesives without compromising PTFE’s inherent properties. Renowned for their non-stick characteristics, these films ensure effortless release, making them ideal for low-friction and non-adhesive applications.

FAQ

Q: Does etching alter PTFE’s properties? 

A: Etching modifies the fluoropolymer’s surface chemistry without altering the bulk material. The process affects only the top few micrometers (µm) of the PTFE thickness, preserving the film’s core physical properties while optimizing surface adhesion.  

Q: What is the appearance of etched PTFE? 

A: Unetched surfaces retain a blue/gray hue (vs. natural white for skived PTFE). Etched sides exhibit a light to dark brown tone with a woodgrain-like texture, which may appear streaked or speckled. Color intensity varies slightly between batches and depends on film thickness.
