Multilayer intumescent sheet |
摘要 |
A multilayer intumescent mat or sheet (30) is useful for mounting a pollution control device (20) or as a firestop. In one aspect, the multilayer intumescent sheet (30) of the invention comprises a non-moldable flexible non-intumescent layer and a non-moldable flexible intumescent layer comprising an intumescent material wherein the layers form a single sheet without the use of auxiliary bonding means. The mat desirably includes a significant proportion of inorganic fiber containing shot, and small proportions of shot-free inorganic fiber and intumescent material. In another aspect, the multilayer intumescent sheet of the invention comprises a first non-moldable intumescent layer comprising a first intumescent material and a second non-moldable intumescent layer comprising a second intumescent material, the first and second intumescent materials being different, wherein the layers form a single sheet without the use of auxiliary bonding means. The invention also provides a pollution control device comprising a multilayer sheet of the invention disposed between a monolith and a housing. <IMAGE> |
