VISCOUS FLUID FOR VIBRATION DAMPERS AND VIBRATION DAMPER
To provide viscous fluid for vibration dampers that exhibits high damping force, excellent repeatability, and low temperature dependence, as well as a vibration damper.SOLUTION: Viscous fluid for vibration dampers contains the following (A) and (B), where the (A) is 15 mass% or more and 95 mass% or less and the (B) is 5 mass% or more and 85 mass% or less relative to 100 mass% of the entire polyisobutylene. Also there is provided a vibration damper comprising the same as viscous fluid. (A) High-molecular-weight polyisobutylene with viscosity average molecular weight of 80,000 or more and 110,000 or less. (B) Low-molecular-weight polyisobutylene with number average molecular weight of 10,000 or more and 20,000 or less.SELECTED DRAWING: Figure 1
