WebFeb 8, 2016 · Surface emissivity is the amount of infrared energy emitted by a specific material. It is often expressed as a ratio or percentage of “1” with the “1.0” value being perfect “black body”. A material that emitted heat energy at half that rate, like polyester film, would have a rating of .50 or 50%. WebSince the emissivity of a material will vary as a function of temperature and surface finish, the values in these tables should be used only as a guide for relative or delta …

WebEmissivity value for acrylic. The emissivity value for acrylic ranges from about 0.90 to 0.95. For thin material, less than 1/8" down to film thickness, the emissivity can be below 0.90. Emissivity depends on absorption in the IR range, and for thin materials, such as films, the absorption is less in the IR range, due to thickness.
