Self Adhesive Intumescent Fireproof Sealing Strip
The intumescent Seal expands in a fire to seal door frames and glazing applications to help prevent the passage of fire, smoke and toxic gases.
| Material | Expandible graphite and PVC |
| Size | Width: 10-50mm; Thickness: 1-5mm |
| Color Options | Red, brown, white, black |
| Initial Expansion Temp | 199ºC |
| Main Expansion Temp | 347ºC |
| Linear Expansion Ratio | ≥3 times |
| Key Function | Rapid expansion during fire to close door/window cracks; prevents smoke and heat channeling; sound insulation. |
| Application | Fire-proof doors, security doors, heating furnaces, heat sinks, building pipe wells, etc. |
Used in fire door assemblies of timber, steel or composite construction. The intumescent expands rapidly to many times (6 - 30 times) its original size upon contact with fire. It concentrates high pressure in confined spaces, exfoliates slowly to protect itself once activated and provides excellent insulation. When correctly positioned, the seals prevent the passage of flames, hot smoke, and fumes.
