PVC Intumesent Seal
DETAILS

The intumescent Seal that expands in a fire to seal door frames and glazing applications to help prevent the passage of fire, smoke and toxic gases.

 

Small Boss has a large range of intumescent seals to suit the OEM and retrofit aftermarket. Intumescent seals are predominantly used in door assemblies manufactured by fire door manufacturers where they incorporate Small boss sealing systems into the door set prior to leaving the factory.

Used in fire door assemblies of timber, steel or composite construction, Small Boss 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 has good insulation properties. When correctly positioned in the door leaf or door frame margin, the seals expand when activated to prevent the passage of flames, hot smoke and fumes from one compartment to another.

Unlike sodium silicate based material, Small Boss’s unique intumescent is unaffected by water making them ideal for application in damp or humid environments. The intumescent is clean, non-toxic and displays outstanding durability and reliability.

Application:

  • Intumescent material expands when heated to seal around objects exposed to fire
  • Smoke seal retards spread of toxic by-products of combustion
  • Documented aging properties
  • Excellent flexibility for easy and cost-effective installation
  • Low flame spread and smoke development
  • Can be cut required length
  • Re-enterable (no special tools required)

Seal Configurations:

Some seals are supplied with self-adhesive backing tape in order to been stuck on the doors or others.
