US 2026/0085175 A1 · MEMBRANE MATERIAL HAVING IMMISCIBLE POLYMERS FOR USE IN OPTICAL FIBER CABLE STRUCTURES

Abstract

Provided are embodiments of an extruded membrane material. The extruded membrane material includes a first thermoplastic polymer and a second thermoplastic polymer. The first thermoplastic polymer and the second thermoplastic polymer are immiscible. The first thermoplastic polymer forms a first phase oriented along an extrusion direction, and the second thermoplastic polymer forms a second phase oriented along the extrusion direction. The first phase is co-continuous with the second phase. Further, the extruded membrane material has a tensile yield strength of at least 10 MPa along the extrusion direction and a peel strength of 4 N or less transverse to the extrusion direction.
