DeWAL DW 216      
Polytetrafluoroethylene      
Product Description:      
Skived from virgin PTFE that has been etched on one side with sodium ammonia. This surface treatment allows PTFE to become a "bondable surface" to other materials. In some applicatons Sodium Ammonia etched materials exhibit somewhat higher bond strengths than those etched with Sodium Naphthalene (D/W 212).
       
Applications for sodium etched PTFE include bonding to elastomers to produce laminated diaphragms, as well as the application of pressure sensitive adhesives in the production of PTFE pressure sensitive tapes.
