【Abstract】 The morphology and structure of the silicone rubber/EPDM foam were studied by SEM and laser focusing microscope and its tensile strength,compression property and damping characteristics were also investigated.The results showed that the better dispersity of the blend was obtained by using silane coupling agent;the density of the blend foam was lower than 0.55 Mg·m -3 ;the pore size distribution was narrow and the mean pore diameter was less than 80 μm;and tensile strength,compression property and damping characteristics of the blend foam were superior to those of silicone rubber foam.更多还原
