Abstract

Silicone rubber (SR) and ethylene-propylene-diene monomer (EPDM) blends were prepared for damping application. The mechanical and thermal properties of the blends are studied. With the increasing content of EPDM, the tensile strength is decreased but elongation at break is increased. By blending with EPDM, tan δ (at 35 to 200°C) of SR is enhanced. However, thermogravimetric analysis results showed the decrease in thermal stability. Scanning electron microscopy study showed the good filler dispersion of the blends with some large silica particles. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
