Title (EN) PTC-EFFECT COMPOSITE MATERIAL, CORRESPONDING PRODUCTION METHOD, AND HEATER DEVICE INCLUDING SUCH MATERIAL
(FR) MATÉRIAU COMPOSITE À EFFET PTC, PROCÉDÉ DE PRODUCTION CORRESPONDANT, ET DISPOSITIF CHAUFFANT COMPRENANT UN TEL MATÉRIAU
Abstract:
(EN) A co-continuous mouldable polymeric composite with PTC effect has a matrix that comprises at least two immiscible polymers (HDPE, POM), and an electrically conductive filler (CB) in the matrix. At least one of said immiscible polymers is high-density polyethylene (HDPE), and at least one other of said immiscible polymers is polyoxymethylene (POM).
(FR) L'invention concerne un composite polymérique moulable co-continu à effet PTC, doté d'une matrice qui comporte au moins deux polymères non miscibles (HDPE, POM), et une charge électriquement conductrice (CB) dans la matrice. Au moins un desdits polymères non miscibles est un polyéthylène à haute densité (HDPE), et au moins un autre desdits polymères non miscibles est un polyoxyméthylène (POM).
