This abstract first appeared for US patent application 18701824 titled 'RESIN SHEET FOR FLEXIBLE FLAT CABLE AND FLEXIBLE FLAT CABLE
Original Abstract Submitted
A resin sheet for a flexible flat cable of the present disclosure comprises one or a plurality of insulating layers and being layered between a plurality of conductors arranged in parallel and a shield layer layered on an outer surface side of parallel arranged surfaces of the plurality of conductors. The resin sheet has a relative dielectric constant of 2.3 or less at 25° C. and 10 GHZ, and a dielectric loss tangent of 0.0014 or less. The resin sheet has a tensile elastic modulus of 40 MPa to 450 MPa. The resin sheet includes a base insulating layer containing a thermoplastic olefinic elastomer as a primary component, and an average thickness of the base insulating layer is 20 μm to 450 μm.
