Abstract

1512766 Insulating foam A C I TECHNICAL CENTRE PTY Ltd 22 Feb 1977 07396/77 Heading C1J A method of producing a high temperature insulating foam comprises forming with sufficient water to produce a gellable foam a mixture of components:- Reinforcing fibre (e.g. glass fibre) 0À5-20 wt. per cent, expanded aggregate (e.g. perlite) 40-95 wt. per cent, bentonite 5-40 wt. per cent; foaming, shaping and drying and firing the foam at lower than 900‹C. and in excess of the temperature at which the bentonite lattice hydroxyl water is lost, the temperature being below that at which a ceramic product is formed.
