DARLYN & FLUEFLEX Flexible expansion joint membranes

DARLYN & FLUEFLEX Flexible expansion joint membranes

Saint-Gobain Performance Plastics pioneered the use of fluoroplastic coated and laminated fabrics in non-metallic expansion joints over 25 years ago. Today, we continue to provide a broad line of expansion joint fabrics for use in a multitude of applications. The flagship of the offering, DARLYN® 1000CB, continues to reign as the most reliable and longest-lasting expansion joint fabric in the harshest of applications – wet scrubbers for flue gas desulphurization units. Other products include CHEMLAM CPI fabrcis designed for use in chemical processing industry applications, which combine a cast PTFE film with various fabrics and q-Guard® flexible insulation jacketing which have the highest level of chemical resistance and are non-combustible.  

  • Engineered design with fine-filament fiberglass fabric for extraordinary strength retention and superior flex properties as well as commerical fabric grades for less critical applications
  • Specially formulated fluoropolymer coatings in FLUEFLEX® and patented blend of perfluoroplastic and fluoroelastomer coatings in DARLYN® provide exceptional protection and crack resistance 
  • Temperature resistance up to 300°C (600°F)
  • Laminated barrier film for reduced permeation of flue gases and excellent barrier properties
  • Insulation option on the hot side of the expansion joint for dramatic inrease of continous usage temperature
