Etched Fluoropolymer Products

High Performance Bonding for Critical Applications

Our etched fluoropolymer products give you the bondable surfaces you need for enhanced performance and durability. Since 1952, Technetics PTFE & Polymer Solutions has been the leader in sodium ammonia fluoropolymer etching, ensuring you receive the long lasting, durable, uniform surface modification you require. When compared to sodium naphthalene processes, our sodium ammonia etching have been proven to be the preferred solution with its superior performance and design to give you the bondable surfaces you need on any fluoropolymer quickly and efficiently.

Etched products are available with one or more treated surfaces — including selective spot etching — on continuous roll films, flat sheet or the compound contours of three-dimensional parts. Our equipment can accommodate most commonly used formats, including:

  • Film rolls up to 50” wide
  • .001" - .0155" thick (tapes)
  • Narrow tapes and thin-walled tubing
  • Irregularly shaped items as large as 5 cubic ft in volume, up to 48” x 96” x 3/4”
  • Slitting & Sheeting


Experienced with all fluoropolymers

Whatever type of virgin or filled fluoropolymer you are using, (PTFE, PFA, FEP, ETFE, PCTFE, PVDF, ECTFE, etc) our innovative etching techniques deliver the precise surface treatment required for an excellent bond every time. Treatment can be accomplished on one or more surfaces, or selectively within close tolerances on films, sheets, tubing or other three-dimensional shapes. Our compounds react with only the surface layer of fluoropolymers ensuring dimension and other properties remain largely unaffected.

Storing Recommendations for Etched Surfaces

Etched surfaces of fluoropolymers have a virtually unlimited shelf life as long as they are handled and stored properly. The proper storage conditions are:

  • Clean – So there is no material to tie-up bond sites
  • Dry – So there are no –OH molecules to bond to
  • Cool (less than 100ºF (38ºC)) - higher temps cause molecules to migrate to the surface where they can tie-up bonds
  • Away from UV light
