PROBLEM TO BE SOLVED: To provide an ethylene-propylene-diene rubber foamed material that has excellent flexibility and heat resistance.SOLUTION: An EPDM foamed material is obtained by foaming a rubber composition containing an EPDM. A rate of change Rof an 80% compressive load value CL2 after being heated at 150°C for 10 days to an 80% compressive load value CL1 before being heated is -50% or more and 50% or less and the 80% compressive load value CL1 before being heated is 0.5 N/cmor more and 10 N/cor less. A sealing material 1 includes an EPDM foamed material 2 and a pressure-sensitive adhesive layer 3 provided on its one face or both faces. |
