XHM203F

The XHM203F stands as a robust solution for large-format fire safety, specifically engineered to bridge significant architectural gaps without compromising on seal integrity or thermal protection. While standard seals often fail at wider clearances, this 15 mm profile is purpose-built for heavy-duty applications where structural movement or design requires a larger seal footprint.

Dynamic Thermal Shielding: At the core of the XHM203F is an intelligent intumescent material encased in premium polyurethane foam. In everyday use, the seal provides a soft, elastic interface that reduces mechanical wear on swinging and sliding doors. When a fire occurs and temperatures surpass 200°C, the core undergoes a rapid chemical expansion. This creates a dense, carbonaceous char that physically plugs gaps of up to 13 mm, forming an airtight shield against high-pressure flames and extreme heat.

Advanced Life Safety Engineering: The primary danger in structural fires is the “chimney effect,” where smoke travels through door perimeters. The XHM203F is lab-tested to maintain total smoke control for over 90 minutes. By maintaining its physical structure even when exposed to 980°C for half an hour, it ensures that fire doors remain a reliable barrier, preventing the migration of toxic gases between compartments and providing a critical safety margin for occupants.

Resilient Architecture: Unlike rigid fire seals, the polyurethane foam construction of the XHM203F offers superior recovery properties. It resists “compression set,” meaning it returns to its original shape even after being compressed for long periods. This ensures that the 10-13 mm gap remains perfectly sealed throughout the life of the door, regardless of seasonal humidity changes or frequent usage cycles.
