Polymethylsiloxane liquid PMS-10 is a transparent, colorless liquid with kinematic viscosity at 20 degree C. of 9-11 poises--the temperature of the scintillation in an open crucible is not lower than 174 degrees C. and the temperature of solidification is not greater than 60 degree C.--it is a composition of linearly structured polymers. According to definition it is a dampening liquid, as well as a high and low-temperature heat carrier for apparatus. Organic factors for the wide utilization of polymethylsiloxane liquid PMS-10 in the capacity of dielectric impregnation of cellicular and paper-film condensers are its high stability, as well as the fact that its electrical characteristics are not normalized by the All-Union State Standard. The table gives electrical characteristics of the liquid according to the data of the electrophysical laboratory; the two figures are (1) a graph of the dependence of the tangent angle of the dielectric losses and dielectrical permeability of the organic silicon liquid PMS-10 upon the temperature, and (2) a graph of the dependence of the specific electrical resistance by the organic silicon liquid PMS-10 upon the temperature.
