Universal HD – ePTFE Gasket Tape

Universal HD – ePTFE Gasket Tape

KWO® Universal HD is gasket tape of mono-directionally expanded pure PTFE with a high density.

The tape is characterised by a rectangular cross-section and a relatively small width. The high density of the material and the special cross-section of the tape allow the sealing of very uneven sealing surfaces even at a low gasket stress.

KWO® Universal HD sealant tape is suitable for delicate sealing applications on surfaces vulnerable to tension, such as glass or ceramics. The tape can also be used to seal weak flanges subject to considerable deformation, for example glass reinforced plastics (GRP), plastic fittings and ventilation facilities.


Advantages

  • Good sealing properties even at low gasket stress
  • Low diffusion leakage
  • Excellent adaptability to all surfaces
  • Easy filling of flange gaps
  • Harmless for food-contact applications

Properties

  • Highest adaptability to uneven surfaces with low pressure
  • For seal applications on materials vulnerable to tension
  • UV resistant; no ageing
  • Non-toxic; biologically inert
  • Non-flammable

Applications

  • Tube flanges, sealing for tanks
  • Air-conditioning
  • Apparatus engineering, compensators
  • Machine housing
  • Chemical reactors
  • Pumps, food processing systems

Certificates

  • Certificated and monitored by TUV
  • Compliant to FDA
  • EC 1935/2004 – Suitable for applications with food contact
