The Difference between PTFE and Expanded PTFE: PTFE:
•
It has no smell of its own.
ePTFE: •
100%virgin PTFE is the material used to produce expanded PTFE.
•
ePTFE as a sealing material can be highly compressed.
•
It can stand strong against creep and cold flow.
•
It can adapt to sealing surfaces easily.
