PTFE is an amazing non-stick material, but when you need to glue it to the surface of another material or 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. Sodiumammonia etching service complies with all applicable commercial, military & federal specifications for the surface treatment of all flouro polymers including: PTFE, PFA, FEP, ETFE, PCTFE, PVDF, PVF etc.
From microchips to full size rolls, flouro polymers 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.
Note: Etched surfaces will discolor to a grown appearance.
Size:
PTFE Etching can be done to any shape or size, most preferred or most commonly used is one side etching Sheet.
