Key Performance Benefits

• Extreme Thermal & Vacuum Stability

   

  Stable performance from deep-cooling cryogenic temperatures up to high-temperature service; low outgassing ideal for high-vacuum systems.
   
• Superior Chemical Resistance

   

  Resists acids, alkalis, hydrocarbons, and corrosive media commonly found in petrochemical and refining environments.
   
• Strong Mechanical Reliability

   

  High compression recovery and low stress relaxation ensure leak-free performance under pressure cycling and long-term service.
   
• Custom Composite Design

   

  Can be laminated with stainless steel or copper alloys for reinforced structural gaskets suitable for heavy-duty flanges and valves.
   

Typical Applications

• Dynamic shaft seals and packing rings for pumps, valves, and compressors
• Custom die-cut flange gaskets for pipelines, reactors, and pressure vessels
• High-vacuum chamber seals and thermal barriers in deep-cooling systems
• Heavy industrial seals for refineries, processing plants, and energy equipment
