PTFE conveyor belts are manufactured using fiberglass cloth as the base substrate, impregnated and coated with polytetrafluoroethylene (PTFE) emulsion to produce base fabric in various specifications, which is then processed through specialized techniques into finished conveyor belts of various dimensions. These belts combine the high-temperature resistance and high tensile strength of fiberglass woven fabric with the outstanding insulation, non-stick, and low-friction properties of PTFE — making them a high-performance, multi-purpose high-temperature conveyor belt solution.

Performance Characteristics

1. Flex Fatigue Resistance
   Excellent resistance to bending and flex fatigue, suitable for use with smaller pulley diameters within machinery.
2. Dimensional Stability & High Tensile Strength
   Superior dimensional stability with an elongation coefficient of less than 5‰, delivering excellent mechanical performance throughout service life.
3. Outstanding Non-Stick Properties
   Virtually nothing adheres to the belt surface; various oil stains, contaminants, and other deposits attached to the surface can be effortlessly cleaned.
4. Exceptional Chemical Corrosion Resistance
   Resistant to strong acids, strong alkalis, aqua regia, and a wide range of organic solvents.
5. Excellent Thermal Resistance
   Capable of long-term continuous operation across a temperature range of -180°C to 300°C without cracking, aging, or combustion.
6. High Electrical Insulation & Additional Properties
   High dielectric insulation performance, low coefficient of friction, non-toxic, odorless, UV-resistant, and anti-static.
