1、Product Performance CharacteristicsHigh-temperature calcium silicate core material for fire and sound insulation doors is a kind of inorganic sheet with very stable physical and chemical properties,
High-temperature calcium silicate core material for fire and sound insulation doors is a kind of inorganic sheet with very stable physical and chemical properties, which has high heat temperature, low thermal conductivity, good heat and sound insulation effect, low bulk density, high specific strength, long-term use without deformation, can be arbitrarily processed and spliced, does not contain asbestos, does not produce toxic gases at high temperatures, no smoke diffusion and other excellent characteristics, is a very suitable core material for fire and sound insulation doors. A green building material. This core material has been widely used in various buildings. The product has been tested by the National Center for Refractory Quality Inspection and Supervision, and its combustion performance has reached the non-combustible A1 level, and its fire resistance limit has reached more than 3 hours, which has won the praise of users.
