Silica and sodium silicate solutions were blended into samples of hydroxy terminated polydimethylsiloxane (PDMS) emulsions, which were then end linked into elastomeric networks. The equilibrium stress-strain isotherms measured in elongation show that silica greatly increased the ultimate properties of the elastomers and were thus effective reinforcing fillers. At high, elongation, the reduced stress for the filled elastomer showed downturns due to debonding between polymer and filler, and upturns due to strain-induced crystallization. The energy for rupture (Er) at high filled elastomer was higher than that of the low one.
