A highly reflective polymeric sheet has been invented which has a metallic appearance but contains no metal. The material can appear chrome-like, or be designed to transmit and reflect light for novel lens applications. The absence of metal waste streams and volatile organic emissions gives this technology significant environmental advantages over competitive methods of bright work or reflector fabrication. This unique optical material is non-corroding, and has the low thermal and electrical conductance of plastic. It is produced by coextruding a large number of alternating layers of polymers having a refractive index difference. This technology offers new degrees of freedom for light control in many applications including lighting reflectors, lenses, display panels, decorative trims, and energy management.
