Excellent fire resistance, thermal insulation, and impact resistance! Achieving fire-resistant structures for road tunnels that comply with international standards.
The "Ceramic Protector" is a high thermal insulation refractory material for road tunnels, primarily composed of alumina cement, fired aggregates, and various fibers, which is pressure-formed and then dried in an Al2O3-SiO2 system. By utilizing high porosity technology, it achieves lightweight while suppressing strength reduction, thereby enhancing the efficiency and labor-saving of installation work. 【Features】 ■ Excellent fire resistance, thermal insulation, and impact resistance ■ Non-combustible material that does not emit harmful gases during a fire ■ Minimal deformation, expansion, and contraction during a fire, reducing heat transfer to tunnel structures ■ Suitable for debris prevention during vehicle collisions ■ Superior safety against wind pressure from vehicle traffic ■ Achieves lightweight while suppressing strength reduction through high porosity technology *For more details, please refer to the PDF document or feel free to contact us.
