Title:
RESIN SHEET FOR FLEXIBLE FLAT CABLE AND FLEXIBLE FLAT CABLE
Document Type and Number:
WIPO Patent Application WO/2023/068110
Kind Code:
A1
Abstract:
A resin sheet for a flexible flat cable according to the present disclosure is layered between a plurality of conductors arranged in parallel and a shield layer layered on the outer surface side of the plane in which the plurality of conductors are arranged in parallel, and has one or more insulating layers. The resin sheet for a flexible flat cable comprises a base insulating layer that has a tensile elastic modulus of 40-450 MPa, a dielectric loss tangent of at most 0.0014, and a relative permittivity of at most 2.3 at 25°C and 10 GHz, and that contains an olefin-based thermoplastic elastomer as the main component thereof. The average thickness of the base insulating layer is 20-450 μm.
