Abstract (en)
Non-asbestos alternatives to asbestos papers comprise a matrix of unfired bail clay which is reinforced by organic web-forming fibres such as cellulose and by either: (i) vitreous fibres derived from wool-form material or (ii) fine particles of a non-fibrous charged-layer-silicate mineral such as mica the whole being bound together by a binder which consists essentially of a synthetic resin of the acrylic or polyvinyl acetate variety.
