XHF06

The XHF06 is engineered for high-performance fire doors that require a substantial volume of intumescent material. Distinguishing itself with a robust 8 mm thickness, this model is designed to provide a massive physical barrier upon activation, making it the premier choice for critical junctions in commercial and industrial fire assemblies.

Dual-Material Performance: The XHF06 utilizes a sophisticated PVC+EVA composite carrier. While the PVC provides the necessary structural rigidity to prevent the strip from sagging or warping in its channel, the EVA integration adds a critical layer of elasticity. This hybrid design ensures that under normal service conditions, the seal acts as a high-performance acoustic and thermal insulator, dampening the sound of closing doors and absorbing mechanical vibrations without the permanent flattening seen in lower-grade materials.

High-Volume Fire Containment: The true power of the XHF06 is revealed during a thermal emergency. As temperatures surpass 200°C, the oversized intumescent core initiates a rapid chemical expansion. Because the starting thickness is a generous 8 mm, the resulting carbonized char creates a high-pressure “weld” that is significantly denser and more robust than thinner alternatives. This expansion effectively bridges substantial gaps between the door and frame, physically blocking flame penetration and the transfer of intense radiant heat.

Life-Safety Smoke Suppression: Beyond flame containment, the XHF06 is a vital component in smoke management strategies. Verified by a 90-minute fire resistance test, the seal prevents any visible smoke leakage around the top and side perimeters of the door. By maintaining this airtight integrity under extreme heat (up to 980°C), it preserves air quality in stairwells and lobbies, providing building occupants with a critical safety margin for successful evacuation.
