Application of titanium dioxide as a filler to regulate the properties of epoxy-novolak foams

Abstract

The influence of titanium dioxide filler on the physical, mechanical and dielectric properties of epoxy-novolac foams of the PEN-I brand has been studied. The dependences of the apparent density, thermomechanical characteristics, and water absorption of structural foams depending on the filler content are analyzed. It is established that by introducing dispersed additives, it is possible to regulate the dielectric constant within specified limits and with high accuracy.
