Zusammenfassung:Epoxy resin moulding compositions for sheathing semiconductor components which are inexpensive to produce and have good processing properties give, without addition of flameproofing agents, flame-resistant moulded materials of high glass transition temperature and low thermal expansion coefficient if they contain the following components: (A) a phosphorus-free aromatic and/or heterocyclic polyepoxy resin, optionally blended with an aliphatic epoxy resin, (B) an epoxide-containing phosphorus compound, (C) an aromatic polyamine as curing agent, and (D) fillers. t
