Glue for Paper Honeycomb Fire Doors - the Fire Test Standard
In the realm of building safety, a fire door stands as the first line of defense. Yet, the true heroism of an exceptional fire door lies not only in its robust panels but also in an unseen core component: the specialized adhesive that bonds its heart—the paper honeycomb structure.
While paper honeycomb is prized for being a lightweight, strong, and eco-friendly core material, its performance in a fire emergency depends entirely on one critical factor: the reliability of the adhesive holding it together. Conventional adhesives can fail catastrophically under intense heat—softening, melting, or even burning away—causing the door's structure to collapse when it's needed most.
