Bonding Fluoroplastic Parts to Metals

We manufacture PTFE and other fluoroplastic parts. We have been requested to make parts that can be bonded to metals. Is there a good adhesive, some sort of additive to the PTFE, or a surface treatment that we can use?

Polytetrafluoroethylene (PTFE) is a high-performance plastic used in a variety of industries, particularly for its heat and chemical resistance and “non-stick” properties. However, PTFE has a low surface energy that does not allow adhesives to wet its surface and subsequently bond.

We are using epoxy adhesives to bond steel substrates that are exposed periodically to both 150˚C and as low as 0˚C. Our problem is in maintaining adhesion to the two steel surfaces at such divergent temperatures because of the response of materials to thermal conditions when going through heating and cooling cycles. Do you have any suggestions?
