Magnetorheological elastomer is used in vibration isolation and damping systems; it is promising to use a platform of active vibration isolation in a vacuum to provide vibration protection for the research object. Polymer is a composite material whose rheological properties can change under the influence of a directed magnetic field. For the correct operation of the platform, the constancy of mechanical properties is necessary, which can change during degassing with increasing temperature. The paper presents the results of studies of the mechanical properties of MRE with various compositions prior to degassing in a vacuum. It was found that the elastic modulus of the polymer directly depends on the concentration of filler particles, and no dependence on the presence of surfactants was found.
