Fire stop sealants

How do HEATSHIELD S500 and GS1220 Fire Stop Sealants work?

When exposed to elevated temperatures of a fire situation, the intumescent material contained in the sealants activates and expands to seal gaps and voids around degrading services, and this prevents the spread of fire and hot gases from one compartment to another.
