How are fluoropolymers etched?
There are several methods available for etching fluoropolymers. The most common involve the use of reactive sodium ions to “strip” the fluorine molecules from the surface of the fluoropolymer replacing them with other molecules allowing the etched surface to be bonded to other materials using standard industry practices. The etching process only penetrates a few angstroms into the polymer surface creating a bondable surface without affecting the material properties. CEI manufactures a full range of sodium naphthalene based etchants for all of your etching needs.
