Patent ID: 6890970

Claim:
A thermal conductive material comprising: an unvulcanized ethylene-propylene-diene terpolymer organic material; and a filler having a higher thermal conductivity than the unvulcanized ethylene-propylene-diene terpolymer organic material, wherein the thermal conductive material is plasticized at a temperature in the range of 30-65° C. and the thermal conductive material changes form to flexibly correspond to a form of a surface of a member with which the thermal conductive material comes in contact; and the unvulcanized ethylene-propylene-diene terpolymer organic material has a melting transition in the range of 30-70° C. and a viscosity at 100° C. is equal to or above 70,000 cP, a weight ratio of the filler to the thermal conductive material is in the range of 30-90 weight %.
