MATERIAL FOR INSULATING SUBSTRATE, PRINTED BOARD, LAMINATE, COPPER FOIL WITH RESIN, COPPER-CLAD LAMINATE, POLYIMIDE FILM, FILM FOR TAB, AND PREPREG

摘要

A material for insulating substrates which is excellent in mechanical properties, dimensional stability, heat resistance, flame retardancy, etc. and, in particular, produces an excellent flame-retardant effect due to the effect of shape retention during combustion. The material for use in producing insulating substrates comprises 100 parts by weight of a thermoplastic resin or a mixture thereof with a thermosetting resin and 0.1 to 100 parts by weight of a phyllosilicate.
