KXT PSS PTFE Skived Sheet – High‑Purity, Virgin PTFE for Demanding Sealing & Insulation Applications
Kaxite Sealing presents the KXT PSS PTFE Skived Sheet – a premium, virgin‑grade polytetrafluoroethylene (PTFE) skived sheet manufactured from high‑quality raw materials. With exceptional chemical inertness, a wide operating temperature range, and excellent dielectric properties, this skived sheet is the material of choice for gasketing, electrical insulation, and corrosion‑resistant linings across multiple industries.
Why KXT PSS? Produced by precision skiving from molded PTFE billets, our sheet offers a smooth, uniform surface with tight thickness tolerances (from 0.25 mm to 1.5 mm). It is 100% virgin PTFE – no recycled material or fillers – ensuring consistent performance in aggressive chemical environments, from cryogenic conditions up to +250 °C (continuous service). Its low coefficient of friction, non‑stick surface, and outstanding resistance to virtually all chemicals (except molten alkali metals and elemental fluorine) make it an ideal sealing and insulating material.
As a leading PTFE skived sheet supplier in China, Kaxite offers standard thicknesses from 0.25 mm to 1.5 mm, with custom dimensions and thicknesses available upon request. Our sheets are widely used in circuit board manufacturing, pump and valve sealing, heavy electrical equipment, and many other applications. Request a free sample or get a wholesale quote today.

Frequently Asked Questions About PTFE Skived Sheets
- Q: What is the difference between skived PTFE sheet and molded PTFE sheet?
- A: Skived PTFE sheet is produced by peeling (skiving) a thin, continuous layer from a molded PTFE billet. This process yields a sheet with very precise thickness control, smooth surface finish, and uniform density. Molded sheets are compression‑molded directly and are typically thicker (≥3 mm) with less tight tolerances. Skived sheets are preferred for gaskets, electrical insulation, and applications requiring thin, consistent thickness.
- Q: What is the maximum continuous operating temperature for PTFE skived sheets?
- A: Virgin PTFE can be used continuously from ‑200°C to +250°C. For short periods, it can withstand up to +300°C, but mechanical properties may degrade. Above +250°C, decomposition begins to occur, releasing toxic fumes, so it is not recommended for continuous service beyond this limit.
- Q: Is PTFE skived sheet FDA approved for food contact?
- A: Yes, our KXT PSS virgin PTFE sheet complies with FDA 21 CFR 177.1550 for repeated food contact applications. It is also USP Class VI certified for pharmaceutical and medical device applications. We can provide documentation upon request.
- Q: Can PTFE skived sheets be used for electrical insulation?
- A: Absolutely. PTFE is an excellent electrical insulator with high dielectric strength (≥20 kV/mm), low dielectric constant, and extremely high surface resistivity. It is widely used in high‑frequency, high‑temperature, and high‑voltage insulation applications such as circuit boards, transformer insulation, and cable wraps.
- Q: What thickness and size options are available?
- A: Standard thicknesses range from 0.25 mm to 1.5 mm (custom up to 5 mm). Standard sheet sizes include 1000×1000 mm, 1200×1200 mm, and rolls up to 1500 mm width. Custom dimensions and die‑cut shapes are available – simply contact us with your drawing or specification.
