    (54) MATERIAL FOR CAPACITY DRINKING
    The invention relates to a process engineer for the production of radio components and can be used in the manufacture of capacitors. A known material for impregnation of capacitors containing an aromatic ester, epoxy resin 1. However, this material has insufficient gas absorption.) The purpose of the invention is to increase the gas absorption. For this purpose, a material for impregnating capacitors containing an aromatic ester, epoxy resin contains a compound from the group of decenes, namely decene or dodecene, or tetradecene, or hexadecene, or octadecene, with the following content of ingredients, wt.%: Epoxy resin 0.01-10 One compound from the group of decenes 5.0 -30 Ester of aromatic ester Else. As the ars-1-ester ester, the material may contain dioctyl phthalate, biphenyl, sulfone. The aromatic ester contains an antioxidant. Before the impregnation of the capacitors, the impregnating agent is heated to 50, and after the impregnation, the capacitors are either kept at this temperature for 8 to 16 hours or heated for the same time.
