Self-supporting insulating end cone liner and pollution control device

A flexible and self-supporting insulating end cone liner comprising resilient and compressible non-intumescent insulating material molded into a single, continuous piece having a three dimensional cone shape, with the insulating material comprising inorganic fibers and an organic binder,

• wherein said insulating end cone liner is dimensioned so as to fill a gap between an inner and outer end cone housing of a pollution control device, such that there is no air space between said insulating end cone liner and either end cone housing, said insulating end cone liner maintains its three dimensional cone shape under the force of gravity when placed unsupported on a level surface, and said insulating end cone liner exhibits a resiliency value of at least about 35 percent when evaluated using the Resiliency Test Method.
