產(chǎn)品說明

D/W 212 is a film , skived from virgin PTFE, that has been etched on one side with sodium naphthalene. This surface treatment allows PTFE, which normally exhibits very poor adhesion, to be bonded to other materials.

The major applications for sodium etched PTFE involve bonding to elastomers to produce laminated diaphragms, as well as the application of pressure sensitive adhesives in the production of PTFE pressure sensitive tapes. In all the above applications, the lamination or adhesive application is usually accomplished with a primer that is specific to the material being applied.
