Core Physical & Chemical Properties

Grade Classification (JB/T 53392-1999)

Key Performance Advantages

• Superior Thermal & Vacuum Stability

   

  Stable performance from deep‑cooling low temperatures to high‑temperature cycling; low outgassing and excellent dimensional stability for high‑vacuum environments.
   
• Strong Chemical Compatibility

   

  Resists acids, alkalis, hydrocarbons, and petroleum media; low sulfur and chlorine prevent alloy corrosion in critical processing equipment.
   
• Excellent Mechanical Sealing Performance

   

  High compressibility and rebound ensure tight sealing even on imperfect flange surfaces; stable under pressure fluctuations and long‑term service.
   
• Customizable Composite Structure

   

  Can be laminated with stainless steel or copper alloy for reinforced gaskets, improving strength for heavy‑duty flange and valve applications.
   

Typical Applications

• Dynamic sealing: shaft packing, valve stem seals, and pump seals
• Custom flange gaskets for pipelines, pressure vessels, and reactors
• Sealing components for high‑vacuum chambers and deep‑cooling systems
• Thermal barriers and static seals in petroleum and heavy industrial facilities
