Abstract

Non-asbestos flexible sheet material suitable for use in gaskets for the cylinder head of an internal combustion engine is made by dewatering on a water-permeable conveyor a layer of aqueous slurry and compressing and drying the dewatered layer, the aqueous slurry employed being one that contains the following ingredients in the following proportions by dry weight: ball clay 35-60% cellulose fibres 2-10% organic polymer binder 5-20% fibrillated poly (aromatic 10-40% amide) fibres r
