摘要：

The article presents the results of study of gas-filled material macrostructure based on urea-formaldehyde resin and liquid glass granular filler, obtained by chemical foaming using a variety of the gas-generating agents. There have been researched the influence of amount and type of the gas-generating agent, ratio of the granular filler to urea-formalde hyde binder on the transverse diameter of pores, coefficient of their shape and degree of inhomogeneity of the foam material structure. There have been determined the optimum gas-generating agent and its amount; the optimum ratio of the granular filler to urea-formaldehyde binder to obtain foam material with homogeneous fine porous structure. © 2017-STC "Institute for Single Crystals".
