PTFE Skived Sheet

Kaxite PTFE Skived Sheet is peeled continuously from a compression-molded cylinder, producing a thin, uniform sheet with consistent thickness and fewer surface defects than molded sheet. Standard thickness ranges from 0.5 mm to 8 mm; sheet sizes include 1000 × 1000 mm, 1200 × 1200 mm and 1500 × 1500 mm, plus roll form at 1.0–1.5 m wide × 10 m or 50 m long. Available in four standard grades — 53-G (virgin), GF (glass fiber), C (carbon) and B (bronze). The material operates from −260 °C up to +260 °C and is inert to almost all industrial chemicals. Thickness tolerance is +0/−0.03 mm at 0.5 mm and +0/−0.10 mm at 6 mm. One-side or two-side etched surface is available for adhesive bonding. Custom thicknesses, sheet sizes and die-cut gaskets are supported. Samples are available for evaluation before bulk orders.

PTFE Skived Sheet — Thin-Gauge Virgin PTFE for Sealing and Insulation

Skived PTFE sheet is peeled continuously from a compression-molded PTFE cylinder, producing a thin, uniform sheet with consistent thickness and fewer surface defects than molded sheet. It is the most economical PTFE sheet form for thicknesses under 3 mm and for large-area linings, gasket cutting and electrical insulation.

Available in five standard grades — 53-G (virgin), GF (glass fiber), C (carbon) and B (bronze) — and in full sheets (1000 × 1000 mm to 1500 × 1500 mm), 10 m or 50 m rolls, and cut-to-size pieces. One-side or two-side etched surface is available for adhesive bonding. Custom thicknesses and sizes are quoted on request.

01 // Available surface options

Standard

Smooth natural surface

The standard skived finish with a low-friction, non-stick surface. Suitable for gaskets, linings, electrical insulation and food contact where adhesive bonding is not required.

Option A

One-side etched

One side is chemically etched to a bondable surface. Used where the sheet is laminated to a metal or rubber backing on one face only.

Option B

Two-side etched

Both sides etched. Used for bonding the sheet to a backing on both faces, or for sandwich construction. Available on request.

04 // Material characteristics

What skived PTFE sheet is good at

Outstanding chemical resistance — inert to almost all industrial chemicals and solvents.
Superb electrical insulating properties, among the best of any plastic.
Wide working temperature range: +260 °C down to liquid-nitrogen temperatures (−260 °C).
Very low coefficient of friction, giving a unique non-stick surface.
High dielectric properties and non-toxic — suitable for food-contact applications.
Excellent thermal stability and stable electrical performance across the temperature range.

Where skived PTFE sheet has limits

Not suitable for wear applications — use filled grades or molded sheet for load-bearing parts.
Difficult to bond without an etched surface — request one- or two-side etching where adhesion is required.
Cold-flow under sustained compression — use envelope or filled sheet for high-pressure sealing.
Thicker sheets (above 6 mm) are generally produced by molding rather than skiving for better dimensional stability.

06 // FAQ

What is the difference between skived sheet and molded sheet?

Skived sheet is peeled from a molded or isostatically pressed cylinder, so it is thinner and more economical for gauges under 3 mm and for large-area linings. Molded sheet is compression molded and sintered to full density — it has better dimensional stability, lower internal stress and superior mechanical properties, making it the preferred form for thick gaskets and precision machining.

Which grade should I choose — 53-G, GF, C or B?

53-G is virgin PTFE and is the default for chemical sealing, food contact and electrical insulation. GF (glass fiber), C (carbon) and B (bronze) are filled grades with improved creep resistance, hardness and wear resistance. They are used for mechanical sealing and load-bearing applications where virgin PTFE would cold-flow or wear quickly.

When do I need an etched surface?

Etching is required when the sheet must be bonded to another material with an adhesive. Standard skived sheet has a very low surface energy and cannot be glued reliably without etching. Request one-side etched where the sheet is bonded on one face, and two-side etched where both faces are bonded.

Can you die-cut or supply cut-to-size pieces?

Yes. We supply cut-to-size pieces, die-cut gaskets and shaped components to drawing. Send DWG, DXF, PDF or a physical sample and we will confirm tooling, unit price and lead time.

Do you provide material certificates and samples?

Yes. Material certificates, dimensional inspection reports and grade documentation are available for production orders. Samples are available for evaluation — please provide the thickness, sheet size or drawing you need, and we will confirm availability and delivery time.
