Study of the influence of the modification of glass microspheres on the properties of syntactic foams based on oligomethylsiloxane

摘要

The dependence of the apparent density of oligomethylsiloxane-filler systems on the size of the microspheres and their bulk density was established. The acid-base method was used to determine the acid-base properties of the surface of fillers and to assess the interaction at the phase boundary. Syntactic foam materials, or spheroplastics, are a special type of gas-filled polymeric material. They consist of a polymer matrix and a filler of hollow spherical particles (called microspheres, or microballoons) distributed in the binder.
