High-temperature-resistant calcium silicate core material for fireproof and soundproof doors is an inorganic sheet material with very stable physical and chemical properties. It features high heat resistance, low thermal conductivity, excellent thermal and sound insulation, low bulk density, high specific strength, long-term deformation resistance, and adaptability to any process and splicing. It is 100% asbestos-free, produces no toxic or harmful gases at high temperatures, and produces no smoke. These excellent properties make it a highly suitable core material for fireproof and soundproof doors, making it a green and environmentally friendly building material.

This core material has been widely used in mid- to high-end fireproof and soundproof doors in various buildings, achieving fire resistance limits of up to 90 minutes, or even over 120 minutes. The product has been exported to countries such as the United States, Canada, and Japan, and has received widespread acclaim from users.
