13 month agoFire expansion strip Graphite fire intumescent seal strip
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.
Graphite fire intumescent seal strips are commonly used in fire-rated doors, windows, walls, and other building elements to maintain the integrity of fire compartments and limit the spread of fire. They are typically used for fire doors, fire windows, fire shutters, fire dampers, fireproof glass curtain wall, light construction accessories.

Expansion factor is 3-5 times, expand rapidly when exposed to fire or high temperature. Excellent graphite material, fireproof and waterproof, Non affected by water and humidity. Assist the building components to have fireproof insulation, such as fire, smoke and heat insulation.
