Abstract

Official abstract text for this publication.

An acoustic building material and method for manufacture incorporates chitosan in an amount sufficient to achieve acceptable physical properties with a reduction in binder and to allow the postindustrial/postconsumer content of the building material to be increased. The chitosan also enhances the dewatering of the building material.

First claim

Opening claim text (preview).

What is claimed is: 1. A ceiling tile formed from an aqueous slurry of ingredients including fiber, filler, binder and chitosan, said ingredients being homogenously dispersed throughout the aqueous slurry for interacting of the chitosan with the other of said slurry ingredients whereby the ceiling tile formed of the aqueous slurry is structurally reinforced by the chitosan at least interacting with the binder as compared with an identically formed ceiling tile of the same slurry in…
