Kaxite skived PTFE Teflon sheet is produced by rotating a large cylindrical PTFE billet on a precision lathe and peeling off a thin, continuous layer with a skiving knife. This mechanical process delivers tighter thickness tolerance, a smoother surface and higher density than molded or expanded PTFE sheet — while keeping the full chemical inertness of virgin PTFE.
Manufactured in Ningbo, China by Kaxite Sealing. Standard thickness 0.5-10 mm, sheet sizes 1M×1M to 1.5M×1.5M, roll format 1M×50M. Available in virgin (natural white) and sodium-etched versions for adhesive bonding. FDA 21 CFR 177.1550, RoHS and REACH certified.
±0.03 mm at 0.5 mm thickness, down to ±0.10 mm at 6 mm — far tighter than molded sheet.
Knife-cut finish is non-porous and smooth — no release marks, no visible surface defects.
Density 2.14-2.20 g/cm³ — the same as premium molded PTFE, and higher than expanded sheet.
Continuous rolls up to 50 metres long — ideal for automated die-cutting and high-volume gasket production.
The default grade. Non-stick, chemically inert, non-aging. Used as a raw material for gaskets, bearings, insulating parts and sliding liners that must not stick to any substrate.
Sodium-etched on one or both sides to create a carbon-rich, bondable surface. Standard epoxy, cyanoacrylate or rubber-based adhesives will bond to it — something ordinary PTFE refuses to do. The non-etched side keeps its full non-stick behaviour.

Skived sheet is the industry standard for die-cutting flat gaskets and full-face flange seals.
High dielectric strength and low loss factor — used in transformers, switchgear and cable insulation.
0.04 friction coefficient — bridge bearings, expansion pads, sliding plates and machine guides.
Etched sheet bonded to steel shells for chemical storage tanks and reactor linings.
FDA-compliant contact surface for conveyor belts, chute liners and sterile equipment.
Skived sheet is a raw material for CNC machining into rings, seals and bespoke components.
Heat sealing bars, packaging equipment and adhesive handling — nothing sticks to virgin PTFE.
Ultra-clean handling, wafer carriers and analytical equipment requiring non-contaminating materials.
