Abstract

Non-asbestos alternatives to starch-bound asbestos papers comprise a matrix of unfired ball clay which is reinforced by fine particles of a non-fibrous charged-layer-slicate mineral such as mica and by organic web-forming fibres such as cellulose, the whole being bound together by hydrolysed starch.
