When triggered by heat between 150°c - 200°c, the pads expand rapidly, achieving a 20-fold volume expansion ratio, while producing a high pressure and volume foam. This reaction prevents fire, smoke, and fumes from penetrating the door via gaps between the ironmongery and the door.
SEALz® lntumescent Hardware Pads are available in natural black finish with a self-adhesive fixing method. Available shapes include Hinges, Lockcases, Strikeplates, Escutcheons, and Door Closers.
SEALz® lntumescent Hardware Pads are tested to and comply with BS476: Part 22 and other international standards for up to 120 minutes fire rating. Note that ironmongery selected for fire rated doors should be duly tested to meet the fire rating requirement for each specific purpose.
