PTFE sheets are manufactured by skiving, molding, or extrusion, offering a wide selection of thicknesses and formats.

Thickness range:

• Thin films: 0.05 mm – 3 mm (skived sheets/films)
• Standard sheets: 3 mm – 50 mm
• Thick molded plates: up to 100 mm+ on request

Sheet sizes:

• Common: 1000 × 1000 mm, 1200 × 1200 mm, and 1220 × 2440 mm (4 × 8 ft)
• Custom-cut panels and rolls available

Surface finishes:

• Smooth natural finish (white, opaque)
• Etched PTFE sheets → for adhesive bonding
• Glass-filled, carbon-filled, or bronze-filled grades → improved wear, stiffness, or conductivity

 PTFE sheets can be supplied in ultra-thin films, standard stock, or thick plates — depending on your application.

PTFE sheets are widely used across industries thanks to their non-stick, chemical-resistant, and insulating properties.

Key industries & applications:

• Chemical processing → Tank linings, gaskets, pump parts, seals
• Electronics & semiconductors → Insulating barriers, circuit protection, dielectric sheets
• Food & pharmaceuticals → FDA-approved non-stick conveyor belts, cutting boards, and lining surfaces
• Aerospace & automotive → Lightweight seals, wear parts, fuel system barriers
• Industrial manufacturing → Sliding bearings, wear strips, anti-friction surfaces

 From chemical tanks to food plants, PTFE sheets are used wherever extreme resistance and non-stick properties are required.

PTFE is one of the most chemically inert and thermally stable plastics available.

Temperature performance:

• Continuous use up to 260 °C
• Cryogenic stability down to -200 °C
• Does not degrade in UV or outdoor conditions

Wear & friction:

• Ultra-low friction surface (non-stick)
• Moderate wear resistance (can be improved with fillers like glass or carbon)
• Excellent anti-seize & anti-galling properties

Chemical resistance:

• Resistant to almost all industrial chemicals, solvents, acids, and bases
• Insoluble in water and most solvents
• Not suitable for molten alkali metals and elemental fluorine

 If you need a plastic that resists nearly everything and performs from cryogenic to high-heat conditions, PTFE sheets are unmatched.

While all are fluoropolymers, PTFE is the benchmark for chemical resistance and temperature stability.

PTFE vs. PFA sheets:

• Both resist up to 260 °C
• PTFE → non-melt-processable, softer, more flexible
• PFA → melt-processable, weldable, more stress-crack resistant

PTFE vs. FEP sheets:

• FEP → extrudable, transparent, service temp up to 200 °C
• PTFE → opaque, higher heat resistance, better creep resistance

PTFE vs. PVDF sheets:

• PVDF → stronger, tougher, lower cost, withstands 150 °C
• PTFE → more chemically inert, withstands 260 °C

 Summary guide:

• Choose PTFE sheets → for maximum chemical and temperature resistance
• Choose PFA sheets → for weldability and purity
• Choose FEP sheets → for clarity and continuous extrusion
• Choose PVDF sheets → for strength, rigidity, and outdoor weatherability

PTFE sheets are highly machinable, though they are not melt-processable like PFA or FEP.

Machining:

• Machines cleanly with sharp tools
• Softness allows easy cutting but requires care to avoid deformation
• Often used as stock for gaskets, seals, and insulating parts

Fabrication:

• Bonding → requires etched PTFE surfaces for adhesives
• Welding → not possible by melt methods (PTFE cannot be thermally welded)
• Skiving → thin films can be produced by peeling from large billets

Modified PTFE options:

• Filled PTFE (glass, carbon, bronze) for improved wear & load-bearing capacity
• Expanded PTFE sheets for sealing (soft, compressible gasket material)

 PTFE sheets are best suited for machining into precision parts, sealing components, and non-stick linings
