Introduction
RESSA intumescent pads for fire collar is used for firestop protection of penetrations of plastic pipes (made of PVC, PP, PE,HDPE) through the fire compartment divisions. The intumescent pads for fire collar consists of flame retardant expansion graphite based materials. It is the ideal material for fire collars which installed outside around the plastic pipe and fixed on the floor or wall.
The plastic pipe has been widely used in all kinds of public and civil buildings. When the fire happens, the hole after plastic pipe becomes the fire spreading channel like a chimney. The flame and smoke will spread from one floor to the tohers, or from one room to other rooms. In a fire attack situation, RESSA intumescent pad for fire collar will expand to 7-30times than original volumn and seal through the plastic pipe hole rapidly. It will prevent the fire and hot gases spreading to the non-fire side of the wall or floor through the hole.
