Overview
Intumescent Fire Proof Sealant is a fireproof sealing material that complies with the GB 23864-2023 standard. Made with intumescent flame-retardant base material as the core, it is a specialized fire protection material used for sealing gaps and holes in construction and industrial scenarios. When exposed to fire, the material expands rapidly to form a dense heat-insulating layer—it not only seals gaps but also blocks the spread of flames, smoke, and high temperatures, making it one of the key materials for enhancing the fire safety of various facilities.
Features
- Does not burn in open flame: It has excellent fire resistance properties and will not burn even when in direct contact with open flame, reducing the risk of fire spread from the source.
- High bonding strength: It has strong adhesion to various substrates (such as metals, building materials, cables, etc.). It does not easily fall off after construction, ensuring long-lasting and stable sealing performance.
- Versatile applicability: It is suitable for sealing gaps/holes in multiple scenarios and on various substrates, with no need for additional auxiliary materials of different specifications.
- Excellent flame retardancy: The heat-insulating layer formed after intumescence in fire can effectively block the spread of flames and high temperatures, providing outstanding flame-retardant protection.
- Good flexibility: The material has excellent elasticity, can adapt to slight deformation of the substrate, and is not prone to cracking due to vibration, thermal expansion, or contraction, ensuring high sealing reliability.
Applications
It is mainly used in fire sealing projects for construction and industrial facilities, including: sealing gaps in building walls/floor slabs, and holes where pipes (cables, air ducts, water pipes, etc.) pass through walls/floor slabs; sealing cable gaps in power and communication equipment rooms; and sealing fire compartment areas in scenarios such as chemical plants and transportation facilities (tunnels, subways). It can effectively enhance the fire compartmentation capability of various areas and reduce the risk of fire spread.
