Frequently Asked Questions
Q: What is the difference between PTFE and Teflon?
A: PTFE is the chemical name for Polytetrafluoroethylene. "Teflon" is a registered brand name owned by Chemours. In industrial contexts, "Teflon" is often used generically to refer to PTFE materials. Kaxite produces high‑quality PTFE sheets that match or exceed Teflon brand performance.
Q: What is the difference between skived and molded PTFE sheet?
A: Skived PTFE is peeled from a billet, producing thin, smooth sheets with excellent dimensional stability (down to 0.05mm). Molded PTFE is compression‑molded, suitable for thicker sheets (1‑100mm) and general‑purpose applications.
Q: When should I choose a filled PTFE sheet over virgin PTFE?
A: Filled PTFE (glass, carbon, bronze) offers improved wear resistance, reduced creep (cold flow), increased compressive strength, and enhanced thermal conductivity. Choose filled grades for high‑load bearing, wear‑prone, or heavy‑duty applications.
Q: Do you provide material certificates?
A: Absolutely. Every batch is supplied with a material test certificate detailing density, tensile, elongation, dielectric strength, and other key properties per international standards.
