Excellent Chemical resistance

Soft , flexible , light clamping force to seal

Easy cutting , normal scissors or knives only can be processed

High – intensity , fibrosis , 3D structure ; which greatly reduce the cold flow creep


  • Gasket making convenient.
  • Low requirement for the bolt pretightening force.
  • High temperature resistance, long service life.
  • Ideal for damaged flanges, irregular flanges, and glass-ceramic flanges.
  • No pollution for fluid.
  • Chemical corrosion resistance.
