DeWal Industries 213
Skived PTFE Tape

General Information
213 is a 2 mil, film skived from virgin PTFE, that has been etched on one side with Sodium Naphthalene after which a primer has been applied to enhance bonding to elastomers and pressure sensitive adhesives. This surface treatment allows the PTFE which normally exhibits very poor adhesion to be bonded to other materials. The primary 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.

View Case Studies

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.

It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.

Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.

Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
