How do HEATSHIELD PPS Transit Sleeves work?

When exposed to elevated temperatures of a fire situation, the intumescent material contained in the PPS Transit Sleeve activates and expands, to fill and seal the sleeve and gaps and voids around degrading cables. Once fully activated the intumescent material forms a plug which prevents the spread of fire and hot gases from one compartment to another. The foam end plugs can help to reduce cold smoke transmission.
