ABSTRACT:
Dispersion polymerized PTFE itself, if provided in an unfused state, is sufficiently capable of acting as a pressure sensitive adhesive to facilitate the formation of an initial mechanical bond between components of a laminate such that it may be subsequently heat treated in a relatively short period of time to produce a well-bonded final laminate. This fact makes it possible to prepare a laminate comprising at least one layer containing PTFE by the steps of:
