Combining fire resistance and airtightness. Elastic sealing material for sealing gaps in gas extinguishing systems.
This is a modified silicone-based elastic sealing material that expands when heated and suppresses flames. It compensates for the weaknesses of non-combustible materials in terms of airtightness and flexibility, making it suitable for use in interior and exterior applications.
This product, known for its high reliability as a "fireproof sealant," has been confirmed to have a "1-hour fire resistance for walls" and a "2-hour fire resistance for floors" through fire tests conducted by the Japan Building Disaster Prevention Association. During a fire, the sealing material expands and hardens due to high temperatures, suppressing flame penetration from joints and the rise in temperature on the backside. Under normal conditions, it possesses flexible rubber elasticity, demonstrating adaptability and water-stopping effects at joint areas in construction. Additionally, this product is a non-formaldehyde material certified as JIA F☆☆☆☆, suitable for building applications, and is a "health-conscious housing product" that does not contain 13 types of VOCs. 【Features】 ■ Performance confirmed under the following conditions in fire resistance tests at the Japan Building Disaster Prevention Association: - 1-hour fire resistance: Joint width 10mm × Joint depth 10mm - 2-hour fire resistance: Joint width 20mm × Joint depth 20mm *For more details, please download the PDF or feel free to contact us.
