FOAMED RESIN HAVING ELECTRICAL CONDUCTIVITY

摘要

PROBLEM TO BE SOLVED: To provide a foamed resin having excellent flexibility and conductivity, easy in shape processing and can be used as a conductive cushioning sealing material and further can bury the minute clearance between highly densified electric parts.

SOLUTION: In the foamed resin, volume resistivity is≤1010Ωcm and load for impact resilience at the time of 50% compression is≤5 N/cm2. The surface resistivity of the foamed resin is≤1010Ω/sq. preferably. In addition, an apparent density of the foamed resin is preferably 0.01-0.15 g/cm3. Moreover, an expansion ratio of the foamed resin is preferably≥9 times.
