Lightweight composite material consisting of two sheets of aluminum bonded to a core of polyethylene, polyurethane, or other material. This is typically used as milled panels for exterior cladding, interior surface applications, and signage. Aluminum composite material is increasingly used in museum storage and exhibition applications as a non-VOC-emitting material, safe for use around all museum objects. For the panels that aluminum composite material forms, use "aluminum composite panels."
