Frequently Asked Questions – PTFE Sheet
What is the maximum temperature for PTFE sheets?
PTFE sheets can withstand continuous service up to 260°C (500°F) and intermittent up to 300°C. For higher temperatures, consider ceramic or mica‑filled alternatives.
Are Kaxite PTFE sheets FDA‑approved?
Yes, our pure and expanded PTFE sheets comply with FDA regulation 21 CFR 177.1550 and USP Class VI for food, beverage, and pharmaceutical contact applications.
Can you produce custom thickness and size?
Absolutely. We offer custom thickness from 0.05 mm to 50 mm and sheet dimensions up to 1500×1500 mm. Larger sizes are available upon request.
What surface treatments are available?
We provide sodium etch (one‑side or two‑sides) for adhesive bonding, as well as acrylic pressure‑sensitive adhesive backing for easy installation.
What is the difference between molded and skived PTFE sheets?
Molded sheets are compression‑molded and then sintered, offering thicker dimensions and high structural integrity. Skived sheets are produced by skiving a molded block, resulting in thin, uniform sheets with excellent surface finish.
