What fabric is used in manufacturing expansion joints?

The fabric is comprised of various layers:

  1. Inner layer: Comprised of highly thermal and abrasive resistant fabric material. It is usually used for 1000 degrees F plus working conditions.
  2.  PTFE/Fiberglass Composite LFP Corrosion Lined: The LFP Corrosion liner is 100 percent PTFE material that is capable of resisting the stress cracking caused by flexing and severe temperature fluctuation.
  3. Thermal Ceramics Fiber Blanket: This layer provides excellent resistance. It can withstand temperatures up to 2300 degrees F and chemical attack.
