Nanoscale ir absorbers in multilayer moldings

Abstract

Multilayer moldings (1) comprising an outer layer (2) comprising a thermoplastic polymer and at least one nanoscale IR absorber (8), and also an inner layer (3) arranged under the outer layer (2) and comprising a thermoplastic polymer. Multilayer molding (1) where the following are used as additional additives: UV absorbers, non-particulate organic IR absorbers, stabilizers, antioxidants, colorants, inorganic salts, pearl-luster pigments, NIR-reflective substances, antifogging agents, or fillers. Multilayer moldings (1) taking the form of a panel or sheeting. Process for the production of a multilayer molding (1) via coextrusion of the outer layer (2) and of the inner layer (3). Use of multilayer moldings in heat management, in agriculture, as window constituent, or as constituent of panels having cavities, twin-web panels, multi-web sandwich panels, or solid panels.
