FIELD: production of polymeric compositions applied to pressurization of electrodevices. ^ SUBSTANCE: the invention is pertaining to the field of production of polymeric compositions applied to pressurization of electrodevices, for example, of low-voltage and high-voltage coils of transformers, chokes, etc. The polymeric composition includes a titaniumsiliconorganic oligomer, a KP-303 compound based on oligostheracrylate and a non-saturated epoxy-ether resin. The technical result of the offered invention is an increase of the maximal operating temperature, a decrease of a temperature coefficient of expansion, an increase of the heat conduction, provision of crack- resistance and positive stability to a heat shock. The declared technical task is reached due to the fact, that the composition additionally contains quartz, aluminum oxide, talcum. ^ EFFECT: the invention ensures an increased maximal operating temperature, a decreased temperature coefficient of expansion, an increase of the heat conduction, provision of crack- resistance and positive stability to a heat shock. ^ 2 tbl |
