1. An insulating material, comprising:
- a mass of fibers, said fibers comprising non-thermoplastic fibers and thermoplastic fibers; and
a plurality of nodes comprised of melted thermoplastic fibers in said mass of fibers, said nodes at least partially surrounding and thereby linking portions of at least some adjoining non-thermoplastic fibers, wherein said insulating material has a density of between approximately 0.1 and 3.0 lbs/ft3.

Abstract
A durable, low-density, high performance insulating material is suitable for use as a high temperature thermal and acoustic insulation. The insulation includes fiber batting made with non-thermoplastic fibers or blends of fibers such as aramid fibers and ceramic fibers, which are bound within at least some interstices by high temperature non-flammable thermoplastic binder such as polyphenylene sulfide. In addition, a fireblocking layer can be provided on at least one surface of the insulation to further improve fire ablation or flame retardance.
