Frequently Asked Questions

  • PTFE (polytetrafluoroethylene) coated fabrics are materials—often fiberglass or other high-performance textiles - coated with a layer of PTFE. This coating delivers non-stick, chemical-resistant, and high-temperature properties. These fabrics are available in various thicknesses, surface finishes, and grades, tailored for applications ranging from food processing and packaging to industrial release sheets and gaskets.

    • Non-stick surface for easy release and cleaning.

    • High temperature resistance (operating up to ~260°C).

    • Outstanding chemical and UV resistance.

    • Excellent electrical insulation.

    • Durability and dimensional stability, even under stress.

    • Food processing (release sheets, conveyor belts)

    • Heat sealing and packaging

    • Gasket materials

    • Electrical insulation

    • Composite bonding in electronics and manufacturing

  • PTFE coated tapes are pressure-sensitive adhesive products comprised of PTFE film or PTFE-coated fabric with a silicone or acrylic adhesive backing. They are non-stick (ideal release surfaces), chemically resistant, tolerate continuous high temperatures, and provide electrical insulation.

    • As release liners in packaging and laminating.

    • In heat sealing machines.

    • As a low-friction, non-stick wrapping for wires and cables.

    • In masking applications during thermal spraying due to their heat and abrasion resistance

  • PTFE belts are conveyor belts made from PTFE-coated glass fabrics, offering excellent non-stick, durability, and resistance to extreme heat. They are commonly used in food, textile, and industrial drying applications where high performance and longevity are vital.

    Key features of PTFE belts:

    • Non-stick and easy to clean

    • Suitable for extremely high and low temperatures (from -150°C up to 260°C)

    • Non-flammable and fire resistant

    • Chemically inert and resistant to most substances

    • Available in various thicknesses and widths.

  • Silicone foam is a chemically expanded, closed-cell material made from silicone rubber. It is valued for its vibration damping, thermal insulation, weather resistance, and ability to operate over a wide temperature range (-70°C to 260°C). It is available in sheets, strips, pads, or custom profiles and is used for gaskets, cushioning, soundproofing, and sealing.

    What are the main uses of silicone foam?

    • Gasketing and sealing in automotive, electronics, and industrial devices

    • Cushioning and impact absorption

    • Insulation in high-temperature environments

    • Flame and UV resistance for outdoor uses.

  • Silicone rubber is a solid material (available in solid or sponge variants) prized for its flexibility, extreme temperature tolerance, and inertness. Silicone foam differs by its closed-cell expansion, providing additional compression, low weight, and insulation characteristics.
