Mounting mat and pollution control device with the same |
摘要 |
Non-woven mat including basalt and amorphous refractory ceramic fibers, bio-soluble ceramic fibers, and/or heat-treated silica fibers. Embodiments of the non-woven mat surprisingly have a Resiliency Value after three thermal cycles from 25° C. to 700° C./400° C. of the Real Condition Fixture Test at least 1.1 times greater than the Resiliency Value of a comparable non-woven mat consisting of any individual type of fibers of the non-woven mat. The non-woven mats are useful, for example, in pollution control devices and other thermal insulation applications. |

1. A non-woven mat comprised of a blend comprised of at least 25 percent by weight basalt fibers and at least 10 percent by weight fibers selected from the group consisting of amorphous refractory ceramic fibers, bio-soluble ceramic fibers, heat-treated silica fibers, and mixtures thereof, based on the total weight of the mat, and wherein the non-woven mat is collectively comprised of at least 80 percent by weight of said basalt fibers and said fibers selected from the group consisting of amorphous refractory ceramic fibers, bio-soluble ceramic fibers, heat-treated silica fibers, and mixtures thereof, based on the total weight of the mat. |
