Abstract
Abstract Thermal insulation with improved thermal stability and resistance to punking. The insulation comprises a matrix of mineral fiber bound with a phenolic resin. The phenolic resin is applied to the matrix as an aqueous solution or dispersion of a resole modified with dicyandiamide or melamine, and containing an alkoxymethylaminotriazine and a proteinaceous compound.
