ABSTRACT:
A composition suitable for making acoustical tiles in a water-felting process comprises expanded perlite, clay, a binder component selected from the group consisting of starch, latex, cellulosic fiber and mixtures thereof and optionally mineral wool. The use of an expanded perlite having a relatively high density, preferably between about 9 pounds per cubic foot to about 20 pounds per cubic foot, enables the formation of a suitable slurry with a relatively low amount of water and enables a more complete dewatering of the mat prior to drying.
