A sheet material includes 30-70 wt. % of aramid pulp, 30-70 wt. % of a fire-retardant short fiber material selected from para-aramid, glass fibers, carbon fibers, and PEEK (polyether etherketone), and 0.5-15 wt. % of a polymer binder, wherein the sheet material is a non-woven sheet material having an areal weight of 10-70 g/m. The sheet material is soft, pliable, and light weight. It can be applied as backing onto upholstery material without detrimentally affecting the properties thereof. At the same time, the sheet material has very good fire-retardant properties.

Fire-retardant sheet material

An electrical insulating paper having 40-80 wt % of aramid fibrid, 10-50 wt % of aramid pulp, and 10-50 wt % of aramid short-cut. The aramid pulp is para-aramid pulp with a length of 0.5-6 mm and has a Schopper Riegler value of 15-85; the aramid fibrid is para-aramid fibrid; and the aramid short-cut is para-aramid short-cut. The paper shows a high dielectric strength and tensile index. A method for manufacturing the paper and an insulated conductor that includes the paper.
