Durlon®Virgin PTFE is made with only pure PTFE resins. It has excellent sealability characteristics, cuts easily, and separates cleanly from flanges after use. Durlon® Virgin PTFE demonstrates high dielectric strength.
Durlon® Virgin PTFE sheet gasket material is available in two grades:
Skived; has better physical properties, good electrical insulator and FDA approved
and Reprocessed; recycled PTFE processed into skived or molded sheet

Note: ASTM properties based on 1/16″ sheet thickness except ASTM F38, which is based on 1/32″ sheet thickness. This is a general guide only and should not be the sole means of accepting or rejecting this material. The data listed here falls within the normal range of product properties but should not be used to establish specification limits nor used alone as the basis of design.
*For applications above Class 300, consult your representative.
