| description | A flat sheet electrical heater, preferably obtainable by coextrusion, comprising: a plurality of elongate conductors evenly spaced apart from and substantially parallel to each other, said conductors being embedded within and in contact with an electrically semiconductive composition with a positive temperature coefficient comprising a polyethylene, polypropylene or a mixture thereof and a conductive filler wherein the distance between elongate conductors is 20 to 150 mm, wherein said conductors are preferably parallel with the machine direction of the semiconductive composition.
La présente invention concerne un dispositif de chauffage électrique à feuille plate, pouvant être obtenu de préférence par coextrusion, comprenant : une pluralité de conducteurs allongés espacés régulièrement les uns des autres et sensiblement parallèles les uns aux autres, lesdits conducteurs étant intégrés dans et en contact avec une composition électriquement semi-conductrice à coefficient de température positif comprenant un polyéthylène, un polypropylène ou un mélange de ceux-ci et une charge conductrice, la distance entre les conducteurs allongés étant de 20 à 150 mm, lesdits conducteurs étant de préférence parallèles au sens machine de la composition semi-conductrice. |
