Noninflammable thermal insulation mouldings - based on perlite granules in resin binder

Abstract

Abstract Lightweight, esp wallboard, material, which can be worked using the same tools as for wood, is a mixture of expanded perlite granules in a U-F resin binder hot pressed into boards at pressures which leave at least the majority of the granules uncompressed. Mineral fibres, esp asbestos or glass may be included in this case the fibres are kneaded with an aq. colloidal soln of the resin to form a mass into which the perlite granules are mixed homogeneously.
