The Fire retardant sealing “Multi Profile System (MPS.)”- IBMO 
 
The Multi Profile System is the fire retardant sealing system for head and bulkhead cable and pipe penetrations. One of the main advantages of this system is that only one type of profile is required, irrespective of cable’s/pipe’s sizes. It will save time a lot.
When exposed to fire, the intumescent character of profiles will expand to close the gap and eliminatefurther spread of smoke and fire.
