Claims
- 1. A heat- and flame-resistant conductive sheet consisting of a laminate of a conductive layer from a paper stock consisting of poly-metaphenylene isophthalamide fibrids, from 0.3 to 170 g/m.sup.2 conducting fibers and optionally poly-metaphenylene isophthalamide floc, said conductive layer having an area resistivity of not more than 10.sup.5 ohm/.sub.-- and on one or both sides of said conductive layer, an electrically insulating layer from a paper stock consisting of poly-metaphenylene isophthalamide fibrids and floc, there being no adhesive employed in the laminate.
- 2. A heat- and flame-resistant conductive sheet of claim 1 in which there is from 0.3 to 8 grams/m.sup.2 of conducting fibers and the area resistivity of the conductive layer is not more than 10.sup.5 ohm/.sub.--.
- 3. A heat- and flame-resistant conductive sheet of claim 1 in which there is from 8 to 170 grams/m.sup.2 of conducting fibers and the area resistivity of the conductive layer is not more than 3.times.10.sup.0 ohm/.sub.--.
- 4. A heat- and flame-resistant conductive sheet of claim 1 wherein the conductive fibers are stainless steel fibers.
