XHM210F

The XHM210F series is a heavy-duty fire safety solution engineered to balance the mechanical demands of high-traffic commercial doors with the stringent requirements of modern fire codes. With its 13 mm profile width, this seal is specifically calibrated for mid-range clearances where a tight, high-pressure seal is required to maintain both acoustic privacy and thermal safety.

Advanced Thermal Reactivity: The core of the XHM210F acts as an “intelligent” fire wall. Under normal ambient conditions, the polyurethane foam provides a soft, elastic interface that dampens door impact and seals against drafts. However, when fire causes temperatures to surge beyond 200°C, the hidden intumescent core triggers a chemical reaction. It swells to three times its original size, transforming into a rigid, carbonized barrier that physically plugs the 2.5–3.7 mm gap, preventing the passage of flames and heat radiation.

Total Smoke Sequestration: Smoke inhalation is the leading cause of fatalities in structural fires. The XHM210F is purpose-built to eliminate this risk by maintaining a smoke-tight perimeter for over 90 minutes. Rigorous testing ensures that even under the intense pressure of a developing fire, no visible smoke escapes through the side or top gaps of the door frame. This performance is vital for protecting stairwells and corridors, ensuring they remain viable as primary evacuation routes.

Reliability Through Extreme Heat: While standard gaskets may ash or melt, the XHM210F maintains its structural integrity at temperatures as high as 980°C. This extreme thermal endurance ensures that the door remains a functional fire barrier throughout the duration of a standard emergency response window. Its durable coating and high-resilience foam core ensure that this protective capability remains intact for years of daily operation without degradation.
