Heat expansion performance: The sodium silicate-based material features stable intumescent performance and expands rapidly when exposed to high heat.
Fireproof insulation layer: It forms a dense, microporous and non-combustible protective foam layer after expansion, effectively isolating fire sources.
Weather & moisture resistance: Resistant to moisture erosion and various climatic influences, with stable long-term service performance.
Easy processing & installation: Flexible material texture, support cutting and punching, available in multiple specifications and formats, simple and efficient to install.
Multi-protection function: Effectively blocks flames, smoke and high-temperature hot gases to prevent fire and smoke spread.
Widely used in fire-resistant building components, suitable for both wooden and metal building fire protection systems:
1. Fire protection doors and fire-resistant windows (core material & sealing strips)
2. Sealing of gaps, joints and reserved openings in fire-proof structures
3. Fire protection for metal and wooden components of fire-resistant building elements
4. Fire-resistant partition walls and main structural building elements
5. Fire protection glazing door and window systems
6. Wall/floor bulkheads: Sealing pipe, cable and ventilation penetration openings
7. Supporting fire protection accessories: Ventilation grilles, pipe fire collars and other intumescent components
8. Safety box, special safety box,ticket selling machine
It is a new type of fire and heat insulation material composed of a variety of mixed inorganic materials with a sodium silicate base. The board is asbestos-free, environmentally friendly, non-toxic and harmless.
When the temperature reaches 100-120°C, the board begins to expand rapidly, expanding to 8-15 times its original volume with a maximum expansion pressure of 1.5N/mm². It forms a hard, high-strength incombustible silicate foam layer. The material releases water vapor during expansion to achieve an endothermic cooling effect, while fully sealing component gaps and joints to block flames, smoke and heat transfer.
The product integrates three core functions: endothermic cooling, expansion sealing and thermal insulation protection. It features low initial expansion temperature, high expansion pressure, and high-temperature ceramization performance. The formed foam layer is structurally strong, non-combustible, smokeless, non-toxic, and does not scatter or fall off during a fire. It can effectively protect surrounding metal and wooden building components.
Yes. Under normal temperature of 20-40°C, the board is flexible and easy for cutting and punching processing. It supports custom size cutting according to project requirements. Two styles are available: with pressure-sensitive adhesive self-adhesive backing and without self-adhesive backing for flexible installation.
It is specially designed and suitable for Class A fire doors, and widely used in fire-resistant building components for gap sealing, fire prevention, smoke isolation and heat insulation protection.
Absolutely safe and eco-friendly. The material is asbestos-free, and will not produce harmful gas, smoke, flying debris or falling residues in fire conditions, meeting high-standard environmental protection and building fire safety requirements.
