The effect of inert fillers on the properties of porous rubbers

摘要

This work is concerned with the determination of the effect of various inert fillers on the technological, physico-mechanical and thermophysical properties of porous rubbers based on styrene-butadiene rubber. It was found that after the addition of calcium carbonate and fly ash, the crosslink density of the polymer improved by 77 and 35%, respectively. In addition, the apparent density of the sample containing calcium carbonate was 36% lower than the standard, and its thermal conductivity was below 47%. In view of the foregoing, it is worth noting that the rubber obtained after the addition of calcium carbonate was the most cost-effective and porous rubber.
