—— PVC Intumescent seal —— 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.
Used in fire door assemblies of timber, steel or composite construction, Small Boss intumescent expands rapidly to many times(25 times at least) 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.—— Overview —— Brief introduction: 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.
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.—— Specifications —— Product No. Width (mm) Thickness (mm) Package SL1010 10 1 25 M/ROLL SL1015 10 1.5 25 M/ROLL SL1020 10 2 25 M/ROLL SL1240 12 4 15 M/ROLL SL1455 14 5.5 15 M/ROLL SL1510 15 1 25 M/ROLL SL1515 15 1.5 25 M/ROLL SL1520 15 2 25 M/ROLL SL1810 18 1 25 M/ROLL SL2010 20 1 25 M/ROLL SL2015 20 1.5 25 M/ROLL SL2020 20 2 25 M/ROLL SL3020 30 2 25 M/ROLL SL3330 33 3 25 M/ROLL SL3620 36 2 25 M/ROLL SL4020 40 2 25 M/ROLL SL5120 51 2 25 M/ROLL SL40060 400 6 25 M/ROLL —— Advantages —— Application:
