Abstract: An anisotropic polycarbonate foam is disclosed. The polycarbonate foam has a low open cell content, and has improved mechanical properties as specified herein. A process for making an anisotropic polycarbonate foam, can comprise: melting a polycarbonate in an extruder to obtain a molten formulation; injecting a blowing agent into the molten formulation; mixing the molten formulation to obtain a single phase mixture; and extruding the single phase mixture through a die to obtain the anisotropic polycarbonate foam.
