More Information
Summary:This disclosure describes a composition that includes a bulk diffuser that includes a film having a major surface; the film includes a polymer, and a scattering element. The scattering element includes a silicone bead having a mean particle diameter in a range of 2 micrometers (μm) to 9 μm. The linear density of the film is at least 5.1 Wi*μm, wherein the linear density equals the product of the mass fraction of the silicone bead (Wi) and film thickness in micrometers (μm). This disclosure further describes methods of making the film and the bulk diffuser and methods of using the film including, for example, as a bulk diffuser in a sign box.
