FR Graphite Plate is a preformed self-adhesive intumescent plate used to reinstate the fire resistance performance of flexible wall constructions when punctured with plastic wall boxes. It is used where the walls have been provided with apertures for the penetration of conduits and cables into socket boxes, on one or both sides of the wall.
FR Graphite Plate immediately reacts to fire through the heat and automatically expands and fills up the box, preventing fire and smoke from passing through. Fitting FR Graphite Plate will reinstate the fire resistance performance of flexible wall constructions for at least 60 minutes. It also prevents the passage of smoke and fire through electrical conduits between socket boxes.
FR Graphite Plate is available in both circular and square shaped plates.
