PROMASEAL®-LW

ADVANTAGES

  • Creates no pressure on expansion
  • Excellent isolation
  • Free of organic solvents and halogen

Fire Prevention Seal

PROMASEAL®-LW is an intumescent seal with a starting temperature of approx. 300°C, which creates no pressure on expansion and multiplies its volume.


Applications

  • PROMASEAL®-LW is an intumescent seal for glazings.

GENERAL TECHNICAL PROPERTIES

 Colour  Light grey
 Appearance  flexible seal
 Density 1.35 ±0.30g/cm³
 Weight 2.4 ±0.24kg/m²
 Reaction to fire  B2, normal combustible
 Expansion temperature  approx. 300° C
 Expansion ratio  approx. 1:28 – 1:40 (unloaded)
 Expansion pressure Minimum 0.4 N/mm² (300°C)
 Thorn flexibility <10mm (20°C)

Above indicated data of expansion ratio and pressure are taken from the DIBT building material approval. The actual expansion ratio as well as the generated expansion pressure are essentially depending on the fire test of the assembly and also on the joint dimensions of the construction itself.
