One-Side Etched PTFE Sheet
One-side etched sheet is used when one surface must be bonded while the opposite surface retains the low-friction, non-stick and chemical-resistant characteristics of untreated PTFE.
Typical uses include:
- Bonded tank linings
- Pipe linings
- Slide surfaces
- Wear pads
- Rubber-backed seals
- Metal-backed PTFE components
Two-Side Etched PTFE Sheet
Two-side etched sheet is selected when both surfaces require bonding, lamination or coating.
Typical uses include:
- Multilayer laminates
- Composite gasket structures
- Sandwich panels
- Double-sided adhesive assemblies
- Encapsulated barrier layers
Handling and Storage
Etched surfaces should be kept clean and protected from contamination. Oil, dust, moisture and repeated handling can affect bonding results.
Store the material in its protective packaging and avoid touching the treated surface. Adhesive selection and bonding conditions should be verified with trial samples before production.
