Electromagnetic wave suppression sheet for flexible printed circuit board or flexible flat cable and electromagnetic wave suppression adhesive sheet using the same

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave suppression sheet having excellent electromagnetic wave suppression performance over wide band frequencies even when a thickness is small and excellent in flexibility and conductivity.SOLUTION: An electromagnetic wave suppression sheet [I] is made of a resin composition (A) containing an electromagnetic wave suppression material. The resin composition (A) contains a polyurethane resin (a1) whose 100% modulus is 1 to 7 MPa.SELECTED DRAWING: None
