Influence of chemical additives on the properties of polymer foams

Abstract

Products based on thermosetting plastics have a variety of applications. One of the directions is thermal insulation. Filling foams provide excellent thermal insulation, due to the most optimal ratio of weight, strength and durability. Such heat-insulating materials work in a wide range of operating conditions. The article presents data on the study of the effect of chemical additives on the reduction of the acid number and the reduction in the corrosivity of foam plastics. The greatest efficiency in reducing corrosion activity has composition based on dihydrate of stannous chloride (II) with calcium oxide in a ratio of 2: 0.5. The data on the change in the multiplicity of foaming when introducing chemical additives containing the same name cation and an anion of the same name are presented.
