PTFE Belts
PTFE Belts and belting materials are available for applications that require superior release characteristics, permeability for rapid drying, dimensional and thermal stability, and the dynamic strength to stand up to the most rigorous operating conditions. The unique behavior of these materials results in a product that is more practical and cost-effective than conventional belting materials.

PTFE Belts
Release Properties
The release characteristics of PTFE are superior to those of any other high temperature material. This non-stick property is retained over a full range of operating temperatures.
Permeability
Our PTFE Belts combine a maximum amount of open area with good mechanical strength. The result is a very high level of controlled air flow through the belt, maximizing the rate of drying.
Dimensional Stability
The woven reinforcement results in an elongation of approximately 1% under normal mechanical loading, even at temperatures of 550°F. Length distortion is exceptionally low, while width rigidity and stability are enhanced by the high-modulus of the reinforcement.
Thermal Stability
Our PTFE Belts may be used continuously at temperatures up to 550°F without reducing its performance.
Dynamic Strength
Our PTFE Belts have been subjected to static and dynamic tests which indicate that it can withstand all normal operating conditions affecting service life.
Chemical Resistance
PTFE Belt surfaces are unaffected by most chemicals and solvents.
Heat sealed to the belt edge, this reinforcement is available in widths from 1″ to 1-1/2″.
