Textile coating market-silicone applications

Silicones are used on a wide variety of textile coating applications including the coating of fabric bellows. For these applications maximum compression and flexibility in the widest possible range of materials (E.g. Polyester, Kevlar, Norex and Nylon) is important to allow application in the widest possible range of environments. Coated fabric bellows are typically assembled using stitched, glued or through heat-sealing method. Fabric bellows can be made as

  • A folded bellow allowing it to cover multiple sides
  • Round bellow for protecting shafts and other cylindrical machine components
  • A flat bellow to cover a single side
  • Industrial coated fabric bellows are great for providing dust protection
