Study on Damping Properties of Silicone Rubber/CPE Blend Foams

doi:10.19491/j.issn.1001-9278.2012.03.009

Abstract

Abstract: The foams of silicone rubber/CPE blends were prepared via mechanical blending methods. The compatibility of the components, influence of heat treatment time on density, foam structure and damping properties were investigated. The blends of silicone rubber/CPE showed a good compatibility. Compared with neat silicone rubber, the effective damping temperature range (tanδ＞0.3) was broadened from 16℃ to 45℃, the maximum loss factor was increased from 0.43 to 0.68, and the glass transition temperature increased by 13℃. However, the damping properties of the foams were damaged by heat treatment.

Key words: silicone rubber, chlorinated polyethylene, foam, damping property
