Title
(EN) ELECTRICALLY INSULATING H-BN COMPOSITE MATERIAL
(FR) MATÉRIAU COMPOSITE H-BN ÉLECTRIQUEMENT ISOLANT
Abstract
(EN)
The disclosure provides an electrically insulating composite material comprising a thermoplastic or thermoset and hexagonal boron nitride (h-BN). The weight ratio of the thermoplastic or thermoset to h-BN is between 90:10 and 99.5:0.5 and the electrically insulating composite material has a resistivity of at least 1x1012 Ωm at 60°C.
(FR)
L'invention concerne un matériau composite électriquement isolant comprenant un thermoplastique ou un thermodurci et du nitrure de bore hexagonal (h-BN). Le rapport en poids du thermoplastique ou du thermodurci sur h-BN est compris entre 90 : 10 et 99,5 : 0,5 et le matériau composite électriquement isolant a une résistivité d'au moins 1x10-12 Ωm À 60 °C
