Safer Gas Connections Thanks to Kapton®

Safer Gas Connections Thanks to Kapton®

Kapton® polyimide film was selected as the flexible material used in the gas tap because its high temperature resistance offers complete security.

Application Description

Gaz de France commissioned a French company to design a new safety gas tap, the R.O.A.I. (Automatic Shut-off Tap), which when connected by a flexible gas pipe to a domestic appliance should shut off automatically in case of overload. The gas tap features a shut-off device which automatically cuts the gas at a flow rate above a pre-determined level and is fitted with a manual system which resets the automatic shut-off and re-establishes the normal gas flow. Kapton® polyimide film was selected as the flexible material used in the gas tap because its high temperature resistance offers complete security. It retains its elasticity even at high temperatures and it is also fatigue resistant, ensuring efficient functioning of the shut-off valve.

Reasons for Choosing Kapton®

  • High temperature resistance for complete security
  • Retains elasticity at high temperatures
  • Resistance to fatigue
