DeWAL DW216

  • Virgin Skived PTFE, Etched

  • Bondable

DW212, 213, 216

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 applications Sodium Ammonia etched materials exhibit somewhat higher bond strengths than those etched with Sodium Naphthalene (DW 212).

APPLICATION INFORMATION
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.
