  • Patent number: 11846097
    Abstract: A fiber product is described which includes fibers, a binder and a temperature control additive. The fiber product has properties that make it useful for a variety of applications. The fibers may be glass fibers and the product may be a fiberglass insulation product for use in buildings, vehicles, or other structures for acoustic and/or thermal insulation. The fibers may be cellulosic fibers and the product may be a wood board product. The temperature control additive is incorporated into the uncured fiber product to prevent deleterious self-heating during or after binder curing. The temperature control additive undergoes an endothermic process that consumes at least a portion of the energy generated during the exothermic curing reaction.
