LAMINATO IGNIFUGHI E CIRCUITI STAMPATI A BASSO GRADO DI INFIAMMABILITA CON ESSI OTTENUTI |
摘要 |
<p>A laminated material comprises a substrate material containing resin-impregnated layers, a metal foil disposed on said substrate and an arc-retardant layer arranged between the metal foil and the substrate material. The arc-retardant layer is an arc-retardant, crosslinked heat-stable synthetic resinous material consisting of from about 60 to 100% by weight of a heat-stable resin which is free of aromatic groupings or heterocyclic rings containing at least one heteroatom and conjugated double bonds and which is not converted to a graphite-containing structure upon being thermally decomposed.</p> |
