Polylack KG

The product is an intumescent mastic with graphite content that forms a hard, stable foam under the effect of high temperature. When exposed to heat, the material expands to several times its original volume within the filled gaps, creating a fire-resistant and thermally insulating layer that prevents the spread of fire through penetration.

Application:

The product is a versatile fire protection material designed for use in both intumescent and ablative systems. It is primarily utilized for the following functions:

• Service penetrations: It is used for sealing small-diameter combustible pipes and metallic pipes provided with combustible insulation. It is also frequently applied for multilayer pipes, single cables, cable bundles, and various pipes with combustible insulation. Due to its high expansion rate, the product is suitable for filling wider gaps around the services while maintaining fire integrity.

• Linear joint seals: the product is used as a fire-rated sealing component for linear joints at structural junctions, including the connections between wall and floor structures to ensure compartmentation.
