EFFECT OF MICROWAVE RADIATION ON THE STRAIN-STRENGTH PROPERTIES OF POLYURETHANE BINDER BASED ON PDI-3B OLIGOMER

Abstract

The effect of microwave radiation on the vulcanizate of a polyurethane binder based on low molecular weight rubber PDI-3B was studied. Densities of thermal energy of microwave radiation absorbed by the material were calculated. It was shown that an increase in the density of thermal energy absorbed by the sample leads to a significant increase in the deformability of the material, which can be associated with a change in the density of the spatial network Keywords: microwave radiation, binder, polymeric material, rubber, thermal energy density, breaking stress, breaking strain, microwave generator, radiation frequency, radiation power.
