Abstract
A low density, high temperature resistant insulation material that is very thermally efficient, is easily moldable and is unaffected by water. The insulation material is especially suitable for use in aviation, aerospace and automotive applications. The insulation material contains inorganic fiber; inorganic binder; hydrophilic particulate inorganic material; hydrophobic particulate inorganic material; polymer; and preferably a setting agent and an opacifier.
Claims20
An extrudable microporous insulation material comprising about:
- (a) 10-30 wt % inorganic reinforcement fiber;
- (b) 15-35 wt % inorganic binder;
- (c) 10-20 wt % hydrophilic fumed particulate filler and bulking material;
- (d) 25-50 wt % fumed particulate insulation material which has been surface treated to make the material hydrophobic;
- (e) 0.5-5 wt % polymer;
- (f) 0-6 wt % setting agent;
- and
- (g) 0-20 wt % opacifier.
An extrudable microporous insulation material comprising about:
- (a) 18 wt % inorganic reinforcement fiber;
- (b) 19 wt % inorganic binder;
- (c) 15 wt % hydrophilic particulate inorganic filler and bulking material;
- (d) 33 wt % particulate inorganic insulation material which has been surface treated to make the material hydrophobic;
- (e) 4 wt % polymer;
- (f) 1 wt % setting agent;
- and
- (g) 10 wt % opacifier.
