Abstract
A fluororesin sheet is disclosed which comprises an aromatic polyamide pulp and a fluororesin as an essential component, the tensile strength of the fluororesin sheet being not less than about 250 kg/cm.sup.2. A process for producing this fluororesin sheet comprises dispersing the aromatic polyamide pulp and the fluororesin powder in water, adding a coagulating agent which destabilizes the dispersing of the fluororesin powder to the dispersion to deposit the fluororesin powder on the surface of the aromatic polyamide pulp, paper-making, followed by drying to obtain a sheet article, and compressing the sheet article using a roller, followed by heating.
