  • Thermal and/or acoustic insulation materials shaped from silica
    Patent number: 9903109
    Abstract: Thermal and/or acoustic insulation materials based on dried precipitated silica, having a total pore volume of from 1 to 5 cm3/g and optionally containing reinforcing fillers and/or opacifying agents, are prepared by: (A) filtering an aqueous dispersion D containing precipitated silica particles in a filter press, whereby a compacted filter cake is obtained; and then (B) drying the filter cake in the compacted state as obtained after step (A).
    Type: Grant
    Filed: August 24, 2015
    Date of Patent: February 27, 2018
    Assignee: Rhodia Chimie
    Inventors: Julien Hernandez, Catherine Enjalbert
