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.

PTFE tape is a PTFE‑coated film or glass cloth with an adhesive backing, used to provide a non‑stick, low‑friction, and high‑temperature surface on heat seal jaws, guides, chutes, and other contact points in packaging and processing equipment.

PTFE glass cloth tapes use a woven fibreglass backing for higher mechanical strength and durability, making them suitable for heat sealing jaws and wear surfaces, while skived PTFE film tapes provide a smoother, conformable surface for lighter‑duty, low‑friction applications.

For heat seal jaws on flow wrappers, L‑bar sealers, and baggers, PTFE glass cloth tapes are typically preferred because they combine a non‑stick PTFE surface with good wear resistance and dimensional stability under repeated heating and cooling cycles.

PTFE glass cloth and coated fabric products are designed for continuous service in high‑temperature environments, such as heat sealing and conveyor applications, where they maintain non‑stick performance and dimensional stability.

Thinner PTFE tapes are suited to applications needing good heat transfer and conformability on seal jaws, while thicker tapes and fabrics are better for abrasive or high‑load surfaces where longer wear life is critical.

Many PTFE coated fabrics and tapes from our principals are designed for use in food processing equipment such as baking liners, conveyors, and grilling belts, where non‑stick, high‑temperature, and chemical‑resistant properties are required; suitability for direct food contact depends on the specific grade.

Yes, PTFE coated fabrics can be supplied in a range of grades, including anti‑static, porous, and open mesh constructions for applications requiring static control or airflow, such as drying, curing, and filtration processes.

Brown International can supply PTFE adhesive tapes and coated fabrics slit or cut to customer‑specified widths to suit particular seal bars, guide rails, and conveyor widths, helping reduce trimming and installation time on site.

For non‑stick conveyor surfaces in baking, grilling, or drying lines, PTFE coated fabrics and PTFE process belts are typically used, with solid or open‑mesh belt constructions selected based on whether product support or airflow is the priority.

PTFE tape is ideal for localised non‑stick and wear surfaces such as seal jaws and guides, while PTFE coated fabric belts are better suited for continuous conveying applications where the product is carried through ovens, dryers, or lamination zones.
