Skived PTFE Sheet – Precision Engineered for Critical Sealing
Ningbo Kaxite Sealing Materials Co., Ltd. delivers high-performance skived PTFE sheets with the tightest thickness tolerance (±0.05 mm) and superior surface finish, setting the benchmark for reliability in demanding sealing and insulation applications. With over 15 years of PTFE processing expertise, our skiving technology ensures consistent quality roll after roll – a critical advantage for engineers in chemical, pharmaceutical, semiconductor, food & beverage, and oil & gas industries.
Unlike compression-moulded sheets, our skived PTFE offers smoother surfaces, reduced permeability, and unparalleled dimensional stability – making it the preferred choice for gasket cutting, flange liners, and electrical insulation. We combine ISO 9001:2015 quality management with responsive customisation, ensuring you receive the right material, on time, at competitive wholesale prices.
Why Choose Our Skived PTFE Sheet?
Precision Skived Finish – ±0.05 mm tolerance, Ra ≤ 0.8 μm surface for reliable compression
Total Chemical Inertness – Resists all acids, bases, solvents, and aggressive media (except molten alkali metals)
Broad Temperature Range – Continuous service from –200 °C to +260 °C; short peaks up to +300 °C
Exceptionally Low Friction – Dynamic COF 0.04–0.08 (against steel), minimises wear and galling
Multiple Grades – Virgin, modified, glass‑filled, carbon‑filled, bronze‑filled, and FDA‑compliant
UL 94 V-0 & Low Outgassing – Self‑extinguishing and vacuum‑compatible for clean environments

Frequently Asked Questions
Q: Skived vs. compression‑moulded – what's the real difference?
A: Skiving produces a continuous sheet with superior surface finish (Ra ≤0.8 μm) and tighter thickness tolerance (±0.05 mm) compared to compression‑moulded (±0.15 mm). This translates to better gasket compression, fewer leaks, and longer service life.
Q: Maximum continuous operating temperature?
A: –200 °C to +260 °C continuous; short‑term excursions up to +300 °C are permissible, but we recommend confirming with our engineers for your specific thermal cycling profile.
Q: Do you offer FDA‑compliant skived PTFE?
A: Yes. Our virgin and modified grades can be supplied with FDA 21 CFR 177.1550 certification. Please specify the FDA requirement when ordering, and we will provide full compliance documentation.
Q: Typical lead time for custom sizes?
A: Standard sizes – 7‑15 working days. Custom dimensions or filled grades – 15‑25 working days, depending on order volume. Expedited production is available for urgent needs.
Q: Can I get a sample before placing a bulk order?
A: Absolutely. We provide free material samples (shipping cost applies) for quality evaluation. Sample orders are processed within 3‑5 working days.
Q: Is skived PTFE suitable for strong oxidising agents?
A: PTFE is chemically inert and resists virtually all chemicals, including strong oxidising agents, except molten alkali metals and elemental fluorine at elevated temperatures. Our technical team can provide a detailed compatibility chart.
