FS3003 INTUMET™
<< Return to INTUMET Formulations

ZERO developed FS3003 specifically for doors. This rubber matrix material:

  • begins intumescing at the relatively low temperatures where organic materials begin to emit combustible and noxious gases.
  • expands gradually to fill all gaps with moderate force that will not unlatch the door.
  • provides sufficient reservoir capacity to continue intumescing if escape doors are closed again.

Other Applications

  • Oil rig fire doors – FS3003 provides effective protection for the intense heat and flames that these doors must be able to withstand.
  • Eave soffit venting - Integrating FS3003 intumescent fire barrier strips satisfies upgraded California fire code requirements prompted by fire storm losses.
