Open mesh PTFE (Polytetrafluoroethylene) coated fabrics are a type of specialized material used in various industrial applications. PTFE is a synthetic fluoropolymer of tetrafluoroethylene, and it is well-known for its non-stick properties, high temperature resistance, chemical inertness, and low coefficient of friction. These characteristics make it suitable for a wide range of applications, especially in environments where traditional materials would not be effective.
The open mesh PTFE coated fabrics are created by impregnating a woven or non-woven fiberglass fabric with PTFE, resulting in a flexible, durable, and porous material. The mesh design provides several advantages, such as improved airflow, allowing hot air or gases to pass through, and enhanced drainage properties.
Some common applications of open mesh PTFE coated fabrics include:
Conveyor Belts: Open mesh PTFE-coated fabrics are used as conveyor belts in industrial processes, especially where high temperatures are involved, such as in food processing, textile drying, and manufacturing.
Release Sheets: They are used as release sheets in applications where sticky or adhesive materials need to be processed or cured, like in the production of vinyl, rubber, or composites.
Drying and Curing Applications: The non-stick properties of PTFE make it ideal for drying and curing processes, where materials are subjected to high temperatures.
Heat Sealing: PTFE coated fabrics are used as heat sealing belts in packaging industries to provide a clean and non-stick surface during the sealing process.
Screen Printing: In the screen printing industry, open mesh PTFE coated fabrics serve as durable and heat-resistant printing surfaces.
Chemical Processing: These fabrics find applications in chemical processing, where resistance to corrosive chemicals and elevated temperatures is crucial.
The advantages of open mesh PTFE coated fabrics include their ability to withstand temperatures ranging from -73°C (-100°F) to over 260°C (500°F) continuously, and even higher temperatures for short periods. They also have excellent chemical resistance, preventing degradation in harsh environments.
