摘要

Abstract

Eucommia ulmoides gum (EU gum)

known as gutta percha in Southeast Asia

is a natural polymer with double characteristics of rubber and plastic. In present paper

tan

δ-T

curve and hysteresis loss (HL) were chosen to characterize its damping property. The results indicated that its tan

value would increase with rising of temperature when

0℃ and form another damping peak at 40-80℃ besides

peak. This phenomenon resulted from meltage of crystals of EU gum could increase its damping property at ambient-high temperature. Its tan

value even exceeded those of conventional damping rubbers

such as nitrile-butadiene rubber (NBR) and chlorinated isobutene-isoprene rubber (CIIR).
