Fabric Expansion Joints Made of Rugged ChemShield, FlexLam

The fabric components of FlexCom’s fabric expansion joints are made of highly durable and versatile thermoplastic composite fabrics that have exceptional resistance to high temperature, chemical attack and particulate abrasion.

• ChemShield^®. ChemShield is a composite material consisting of a layer of polytetrafluoroethylene (PTFE) thermoplastic film laminated to a PTFE-coated fiberglass cloth, providing excellent temperature and pressure tolerances. ChemShield’s surface is inert to nearly all chemicals and solvents with the exception of molten alkali and gaseous fluorine and is highly resistant to moisture. Due to the extremely low friction coefficient of PTFE, ChemShield is exceptionally resistant to abrasions caused by particulate solids suspended in the gas stream. Chemshield also provides excellent resistance to ultraviolet radiation, oxidation and other forms of atmospheric aging.
• FlexLam^®. FlexLam is a multi-ply fabric created by laminating one or more layers of ChemShield onto a thick, woven fiberglass cloth. FlexLam has superior tensile strength, temperature resistance up to 1000°F and overall durability. The outer layer of ChemShield provides a flexible gas barrier while the inner, nonwoven fiberglass mat provides additional temperature protection.
