FIELD: electrical engineering.
SUBSTANCE: method for producing electrets and parts made from them for sealing systems in tribology, in various instruments and apparatuses such as electret dosimeters, electret filters, as well as in sound-reproducing equipment is proposed to use epoxy resin ED-20 (State Standard GOST 10587-93) cured by polyethylene polyamine (Standard Specifications 6-02-594-85) or mixture of unsaturated polyester resin PN-15 (Standard Specifications TU 6-05-861-73), resin SF-342A, and resin ED-20 as basic binding polymer.
EFFECT: enhanced surface charge saving period and heat resistance of material.
