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.
