Critical Performance Requirements

  • Chemical Compatibility: Resistance to acids, bases, solvents, and aggressive process media
  • Extreme Temperature Stability: Performance from cryogenic to high-temperature processes
  • Low Permeability: Minimize permeation of volatile chemicals
  • Purity Standards: Non-contaminating for pharmaceutical and food-grade applications
  • Long-Term Stability: Maintain properties after prolonged chemical exposure
  • FDA/USP Compliance: Where required for regulated industries

Key Applications

  • Chemical Reactors: Sealing agitator shafts, manways, and ports
  • Pump Systems: Seals for chemical transfer and metering pumps
  • Valve Seals: Ball valves, diaphragm valves, and control valves
  • Storage Tanks: Sealing access points and connections
  • Pipeline Systems: Flange seals and expansion joints
  • Pharmaceutical: Bioreactors and sterile processing
