CA 2492405
The invention relates to a thermal and/or sound insulation product which is made from mineral fibres and which is intended for use at temperatures above 150 ·C, particularly between 200 and 500 ·C, and up to 700 ·C and higher in the case of rock fibres. The inventive product contains at least 1 wt.- %, at least 2 wt.- % or even more than 4 wt.- % of a binder which is obtained from sizing, the resin or resin mixture of which essentially comprises at least one epoxy-type resin with an EEW of between 150 and 2000, preferably at least 160 and/or at most 700 or at least 170 and/or at most 300.
L~invention concerne un produit d~isolation thermique et/ou phonique, à base de fibres minérales pour utilisation à plus de 150~C, notamment entre 200 et 500~C, voire même jusqu~à 700~C et plus dans le cas des fibres de roche, qui comprend au moins 1%, voire au moins 2% et même plus de 4% en poids de liant obtenu à partir d~un encollage dont la résine ou le mélange de résines est contitué(e) substantiellement par au moins une résine de type EPOXY de valeur de EEW comprise entre 150 et 2000, de préférence au moins 160 et/ou au plus 700, voire même au moins 170 et/ou au plus 300.
