Etched PTFE sheet
PTFE is an amazing non-stick material, but what about when you need to glue it to the suface of another material ?
In order to bond standard PTFE to another surface such as stainless steel, a process called "etching" is required. Typical applications would include the lining of chemical process tanks or other equipment used in caustic environments. When bonding is needed, sodium etching is usually the most economical answer. This process uses of a mixture of sodium that is formulated to create a bondable surface both quickly and efficiently.
Sodium etching service complies with all applicable commercial, military & federal specifications for the surface treatment of all fluoropolymers including: PTFE, PFA, FEP, ETFE, PCTFE, PVDF
From microchips to full size rolls, fluoropolymers of any shape or complexity, including tape, sheet, tubing, molded shapes & machined parts of any configuration can be etched & bonded. This treatment can be accomplished on one or more surfaces, or selectively within close tolerances.
- Etched surfaces will discolor to a brown appearance.
- It can be Etched on One Side (EOS)(Standard) or Two Sides (E2S)
