PTFE Fabric

PTFE glass fabric is a high-performance material created by impregnating woven fiberglass fabric with PTFE, resulting in a durable and versatile product. This combination endows the fabric with remarkable attributes, including heat resistance, low friction, excellent electrical properties, and resistance to chemical corrosion.

Applications Across Industries

The versatility of PTFE glass fabric allows it to serve various purposes in different sectors:

  1. Industrial Machinery: PTFE glass fabric is extensively used as conveyor belts in industries requiring high heat resistance and non-stick surfaces. It ensures smooth product transfer, withstands extreme temperatures, and resists adherence of substances, contributing to enhanced operational efficiency.
  2. Food Processing: In the food industry, PTFE glass fabric is employed for applications such as baking sheets, conveyor belts, and other food processing equipment due to its non-stick properties, durability, and compliance with food safety regulations.
  3. Packaging: The fabric finds use in heat sealing applications, offering excellent release properties and durability in heat-sealing equipment, ensuring efficient and clean operations.
  4. Aerospace and Engineering: PTFE glass fabric is utilized in aerospace applications for its electrical insulation properties and as a protective covering for cables and wires. In engineering, it serves as a release liner for composite manufacturing due to its non-stick characteristics.

Unique Benefits of PTFE Glass Fabric

  • Heat Resistance: PTFE glass fabric remains stable and functional across a wide range of temperatures, from extreme cold to high heat, without losing its physical properties.
  • Non-Stick Nature: Its non-stick surface properties prevent adhesion of various substances, making it ideal for applications where cleanliness and smooth operations are crucial.
  • Chemical Resistance: The fabric resists a wide array of chemicals, ensuring durability even in challenging environments.
  • Electrical Insulation: PTFE glass fabric serves as an excellent electrical insulator, ensuring safety in electrical applications.
