Abstract: Loose thermosetting mineral wool containing binding mineral fibers surrounded by a dry layer of thermosetting organic binder and, optionally, non-binding fibers.

Abstract: The present invention relates to a method for manufacturing insulation products based on mineral wool bound by an organic binder, comprising the following successive steps: (a) providing a mineral wool, (b) humidifying the mineral wool, (c) placing the humidified mineral wool fibers in contact with particles of binder comprising a mixture of thermosetting reagents, (d) shaping the mixture of mineral wool and binder particles, and (e) heating the shaped mixture to a temperature and for a period sufficient to allow the condensation of the reagents and the formation of an insulation product based on mineral wool bound by an insoluble and infusible organic binder.

Abstract: The invention relates to a method for manufacturing insulation products based on mineral wool bound by an organic binder, comprising the following successive steps: (a) providing mineral wool at room temperature, (b) applying, to the mineral wool, an aqueous thermosetting binder composition, (c) drying the mineral wool impregnated with the aqueous thermosetting binder composition to obtain thermosetting mineral wool, (d) shaping the thermosetting mineral wool, and (e) heating the shaped thermosetting mineral wool at a temperature for long enough to enable the constituents of the binder to be condensed and an insoluble binder to be formed.
