Electric resistor fabric encapsulated in polymer - esp. in elastomer when flexible resistance heating sheet or panel is required

The resistor fabric consists of a weft of conducting wires woven with a warp of insulating wire or threads, esp. asbestos threads; and the fabric is located between two layers of an organic resin, which keeps the outer air away from the fabric. One pref. resistor consists of a flexible sheet of panel where the resin is an elastomer, esp. a silicone elastomer. The resistor fabric may alternatively be located between two layers of another fabric pre-impregnated with resin, esp. a glass fibre fabric coated with polyester. The three layers are hot pressed to produce a rigid sheet or panel. Used. e.g. as flexible resistance heater sheet which can be bent round an object, or a transparent resistor sheet encapsulated in a polyester. CETTE STRUCTURE EST ESSENTIELLEMENT CONSTITUEE PAR UNE RESISTANCE ELECTRIQUE DE TYPE TISSEE, FORMEE D'UNE TRAME DE FILS CONDUCTEURS 1 TISSES SUR UNE CHAINE DE FILS ISOLANTS 2, ET PAR DEUX COUCHES DE RESINE ORGANIQUE 3 ENFERMANT SOUS VIDE D'AIR LA RESISTANCE TISSEE.
