Firestop pack is a new type of fireproof auxiliary fire-resistant material successfully developed by our company in accordance with national standards. This product can be built into various shapes of firewalls and fireproof layers according to different user requirements, and can also be used to seal holes that require fireproofing. When encountering fire, the substance inside the firestop pack expands upon heating and forms a solid honeycomb structure, effectively controlling the fire within a localized area. Using firestop packs to build partition walls replaces the past use of materials such as bricks, slag wool, and ceramic wool; compared to them, firestop packs have a significant heat insulation effect.
