From laboratory equipment to industrial sealing and electrical isolation, our PTFE discs provide a clean, non-reactive, and long-lasting solution.
A PTFE disc is a flat, round piece of virgin or filled polytetrafluoroethylene, available in various diameters and thicknesses. These discs are cut or machined from PTFE sheets or rods and serve as insulators, sealing pads, gaskets, spacers, or inserts in aggressive chemical or thermal environments.
PTFE's non-stick and inert properties make these discs highly suitable for contamination-sensitive industries such as pharmaceutical, biotech, electronics, and chemical processing.
- Chemically inert: Resistant to virtually all corrosive substances including acids, alkalis, and solvents.
- Thermally stable: Operates reliably from –200°C to +260°C.
- Excellent dielectric properties: Ideal for electrical insulation.
- Non-adhesive surface: Prevents sticking, scaling, or contamination.
- FDA-compliant grades available: Safe for food and pharmaceutical use.
- Custom machining: Available in any diameter, hole pattern, or surface finish.
