Frequently Asked Questions

Q: What is expanded PTFE sheet, and how does it differ from standard PTFE sheet?
A: Expanded PTFE is biaxially oriented to create a fibrous microstructure with equal tensile strength in all directions, offering better conformability, lower creep, and enhanced sealability compared to standard molded PTFE.
Q: What is the maximum continuous service temperature?
A: Expanded PTFE sheet can be used continuously at temperatures up to 260°C (500°F), with short‑term excursions up to 300°C.
Q: Is the sheet suitable for contact with food or pharmaceuticals?
A: Yes, virgin PTFE is FDA compliant (21 CFR 177.1550) and non‑toxic, making it safe for food processing and pharmaceutical applications.
Q: Can you provide custom thicknesses or larger sheet sizes?
A: Absolutely. Kaxite offers OEM custom thicknesses (up to 1/4″ and beyond) and larger sheet dimensions. Contact our engineering team for details.
