XHM207F

The XHM207F series introduces a specialized geometry designed for modern architectural hardware, bridging the gap between high-frequency door operation and rigorous fire safety standards. With its unique 10.5 mm width, this seal is engineered to fit precise routing channels where standard 11 mm or 12 mm strips might be too restrictive, ensuring a flush and professional finish.

Active Volumetric Defense: While traditional door gaskets remain static, the XHM207F is a reactive safety system. During everyday use, the polyurethane foam provides a high-resilience seal that blocks noise, dust, and drafts. However, when exposed to the extreme heat of a fire (over 200°C), the embedded intumescent core undergoes a rapid chemical expansion. This transformation creates a dense, pressurized barrier that effectively welds the gap between the door and the frame shut, starving the fire of oxygen and preventing flame bypass.

Life-Saving Smoke Containment: Statistical data shows that smoke is the primary cause of casualty in structural fires. The XHM207F is specifically validated for its smoke control performance, showing zero leakage across the top and side perimeters during a grueling 90-minute fire resistance test. This critical containment keeps evacuation routes visible and breathable, providing occupants with the time necessary for safe egress and giving emergency services a controlled environment to work in.
