<p>PROBLEM TO BE SOLVED: To provide an open cell rubber material having cut-off performance inserted into a dynamic space or the like, easily following dynamic transit such as a dynamic gap and also capable of preventing the intrusion of water into a dynamic gap or the like and water leakage from a dynamic gap.SOLUTION: The open cell rubber material is obtained by opening the space between cells 2, by film cracks V formed by the breakage of an inter-cel film S0 separating the cells 2 present so as to be largely dispersed into a rubber base material S.</p> |
