Special extrusion fire seal

      'Pyroplex' brand steel fire door sealing strip is specially designed for steel fire door. When there is no fire, the rubber sealing ring plays the role of buffering, sealing and dustproof and sound insulation. When a fire occurs, the fireproof expansion material immediately begins to expand, and continues to expand as the temperature rises, effectively sealing the gap between the door frame and door leaf, and meeting the requirements of fire integrity and heat insulation. The high expansion rate can alleviate the risk of fire due to the increased gap caused by the deformation of the door frame and door leaf.

       The rubber sealing ring, like other plastic shells, melts instantly during a fire and is simultaneously squeezed and suffocated by the rapidly expanding fireproof material. Will not produce open flame burning.
