PTFE Etching Sheet

PTFE Etched 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 ammonia etching is usually the most economical answer. This process uses of a mixture of sodium and ammonia that is formulated to create a bondable surface both quickly and efficiently. Sodium/ammonia etching service complies with all applicable commercial, military & federal specifications for the surface treatment of all fluoropolymers including: PTFE, PFA, FEP, ETFE, PCTFE, PVDF, PVF, & ECTFE.

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.

PTFE can be Etched on One Side (EOS)(Standard) or Two Sides (E2S)
