Saint-Gobain Chemfab® 250GW PTFE Coated Beta Fiberglass with Woven-in Graphite Conveyor Belting
Categories: Ceramic; Glass; Glass Fiber

Material Notes: Description: General Notes on Saint Gobain Belting Products:
Saint Gobain Performance Plastics developed its belting materials 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 the materials results in a product that is more practical and cost-effective than conventional belting materials.
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 belting combines 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: Chemfab® brand belting may be used continuously at temperatures up to 550°F without reducing its performance.
Dynamic Stability: Our belting has been subjected to static and dynamic tests which indicate that it can withstand all normal operating conditions affecting service life.
Chemical Resistance: PTFE surfaces are unaffected by most chemicals and solvents.

Notes on 250GW PTFE Coated Beta Fiberglass with Woven-in Graphite Yarns Conveyor Belting:
Chemfab® 250GW utilizes a tightly woven Beta® fiberglass substrate with a woven-in grid of graphite yarns. Its primary use is for aerospace applications (e.g., space shuttle, international space station). All products in the CHEMFAB® 250 series contain silicone to reduce stiffness. The substrate is woven graphite/Beta fiberglass and the coating material is PTFE (PTFE = polytetrafluoroethylene). All data based on a 0.008 inch test sample.
