201 Intumescent Mat

YESO INTERFIRM 201 RCF intumescent catalyst mat made of refractory ceramic fiber and a small amount of vermiculite reduces the content of vermiculite at the same time increases the proportion of refractory ceramic fiber and appropriately low down the support mat peak expansion force to meet the requirement of thin-wall monolith. YESO INTERFIRM 201 intumescent mats are not only suitable for gasoline engines but also available of some diesel engines catalysts (except SCR).
