ETHYLENE PROPYLENE DIENE RUBBER FOAM AND SEALANT

摘要

PROBLEM TO BE SOLVED: To provide an ethylene propylene diene rubber foam having low density and small compressive permanent set and a sealant containing the same.SOLUTION: An ethylene propylene diene rubber foam is obtained by foaming a rubber composition containing an ethylene propylene diene rubber and a thermoplastic resin having a melting point of 60 to 140°C, where the content of the thermoplastic resin is 5 to 50 pts.mass based on 100 pts.mass and the ethylene propylene diene rubber is an ethylene propylene diene rubber having a diene amount of 4.0 mass% or more.SELECTED DRAWING: Figure 1
