Sheet Material


Top-Chem-2003 is a modified PTFE designed for use in low gasket load applications. Glass microspheres aid the compressibility and general mechanical strength without detrimentally affecting the material’s chemical resistance, and has been developed to be used with glass-lined flanges and other circumstances where compressive load is limited.

Top-Chem-2003 can be used for food, pharmaceutical, and chemically aggressive applications.

Key features

  • High compressibility
  • Consistent material composition
  • Resistant to cold flow


  • Excellent sealing at low stress
  • Superior chemical resistance
  • Conforms easily
  • No ageing of the material

Top-Chem-2003 has TA-Luft (Clean Air) approval.
