Combustion performance and Fireproof performance of Rock Wool
Posted by:Yolanda Date:25.May.2020
Combustion performance refers to whether the material itself is combustible and the reaction during combustion.
According to GB 8624-2006, the burning properties of materials can be divided into: A1, A2, B, C, D, E, F and other 7 levels.
The combustion performance of rock wool products can reach A1 level, that is, the requirements of non-combustible materials.
The melting start temperature of rock wool is above 1000 ° C, and there is no obvious shrinkage deformation at 700 ° C, which ensures the stability of rock wool under high temperature.
Fireproof performance resistance refers to the ability of materials and components to prevent the spread of flames and protect the stability of the structure in the event of a fire. It is mainly expressed by the fire resistance limit. Rock wool of different thicknesses can be combined with other materials to achieve 1-4 hours of fire resistance limit
