Title:
CONDUCTIVE RUBBER COMPOSITION FOR SENSING
Document Type and Number:
WIPO Patent Application WO/2023/026620
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a conductive rubber composition for sensing, that exhibits good responsiveness in terms of the change in the electric resistance value in response to distortion, and that allows accurate detection of cracking. The solution to this problem is a conductive rubber composition for sensing, characterized by containing a rubber component and carbon black, wherein the rubber component contains 80 mass% or more of acrylonitrile-butadiene rubber having an acrylonitrile unit content exceeding 45 mass%, and a loss tangent (tan delta) of 0.6 or less at 1% distortion, and a hysteresis loss (Wd/Ws) at 70% elongation time of 0.43 or more.
