Fluoroplastic Belt Material Guide for Fabric Expansion Joints

left border  

Guide to Selecting a Fluoroplastic Belt Material

  1. Compare the maximum continuous operating temperature of the application against the fabric temperature rating.
  2. If the application has high fly ash or dust loading, select a material with high tensile strength. (Fluoroplastic materials are susceptible to failure from abrasion. In applications where the media includes particulate, a liner must be present.)
  3. If the application is near a fan or anywhere flow turbulence is expected, select a material with high flutter resistance.
  4. In areas of scrubbers or applications that experience condensation of low temperature gases, select a material for wet service.
  5. For areas where corrosion is most severe, we recommend FLEXXCEL HC40.
