202 / 202S Micro-Intumescent Mat

YESO INTERFIRM 202 / 202S micro-intumescent mats made of refractory ceramic fiber and an appropriate amount of vermiculite fully takes into account the elasticity of ceramic fiber and the high-temperature expansion of vermiculite. At lower operating temperatures, the fastening force is provided relying on the elasticity of the ceramic fiber while the temperature rises to 350 ° C vermiculite begins to expand, the expansibility of the vermiculite and the elasticity of the ceramic fiber superimpose each other to meet the stability of the system fastening at high temperature. YESO INTERFIRM 202S micro-intumescent mat present much more better aging performance.
