Graphite fire intumescent seal strips are a type of passive fire protection product used to seal gaps and joints in buildings to prevent the spread of fire and smoke. These sealing strips are made from graphite, which is a non-combustible material.

In normal conditions, the graphite rubber strip remains flexible and can be easily compressed to fill gaps and joints. However, in the event of a fire, the strip expands due to the heat, forming a fire-resistant barrier. This expansion is known as intumescence, and it helps to prevent the passage of fire, smoke, and hot gases through the sealed area.
