FIELD: electric engineering, in particular, impregnated insulating materials, manufacturing of press materials. SUBSTANCE: material has paper base, which consists of 100 weight parts of polyamide fibers, 20-300 weight parts of polyether fiber which linear density is in range of 0.33-0.6 tack and binder which consists of 100 weight parts of condensate of triphenol and epoxy chlorine hydride and contains at least 19.5% of epoxy groups, 5-20 weight parts of tetrabromphenylolpropane (or diphenylsulphone, 1-10 weight parts of composition of triple-fluoride boron and benzylamine (or monoethylamine). EFFECT: increased insulation capacities, decreased inflammability.
