Industrial PTFE Fabrics & Mesh Sheets
Here are some key aspects of non-stick PTFE for custom fabrics and industrial applications:
Non-Stick Properties: PTFE is renowned for its superior non-stick surface, making it suitable for applications where materials need to slide or release easily without sticking. This property minimizes friction and wear, enhances efficiency, and reduces the need for lubricants or release agents.
High-Temperature Resistance: PTFE materials can withstand extreme temperatures, often exceeding 500°F (260°C) without degrading. This characteristic is crucial for applications involving heat sealing, welding, baking, or any process with high-temperature exposure.
Chemical Resistance: PTFE is highly resistant to a wide range of chemicals, acids, and solvents. This resistance ensures that PTFE materials remain unaffected by exposure to corrosive substances, which is vital in chemical processing and industrial environments.
Electrical Insulation: PTFE is an excellent electrical insulator, making it valuable in applications that require electrical insulation, such as wire and cable insulation, gaskets, and electronic components.
Durability: Non-stick PTFE materials are known for their durability and resistance to wear and tear. They have a long service life, reducing the need for frequent replacements.
Versatility: PTFE materials are available in various forms, including sheets, films, tapes, and custom shapes. They can be easily customized and fabricated to meet specific industrial requirements.

FAQs
What are PTFE sheets used for?
PTFE sheets of various sizes and thicknesses have widespread applications:
- Food Service: Fast casual restaurants use PTFE sheets in high-speed contact bun toasters and clamshell grills
- Baking Operations: Commercial and home bakers use PTFE sheets as pan liners for quick release of baked goods
- Textile Industry: Heat sealing applications for garment graphics
- Composite Manufacturing: Release surfaces for molding operations
Â
The versatility of PTFE sheets makes them indispensable in operations requiring consistent release properties and high-temperature resistance.
Can you form a PTFE sheet (what is thermoforming)?
Thermoforming is the process of using heat to form various plastic materials. PTFE can be thermoformed using specialized equipment that employs both heat and pressure. Associated with thermoforming, PTFE can be formed with heat, pressure and adhesive film to create thermo-welded bonds, creating edging or loops in the PTFE sheet for specialized applications.
Does anything stick to PTFE sheets?
Â
By its very nature, PTFE is extremely resistant to adhesion across virtually all materials. This universal adhesion resistance is what makes it valuable in release applications, such as within the foodservice industry. However, with specialized equipment that uses heat and pressure, certain materials can be made to adhere to PTFE surfaces to suit specific industrial purposes.
