solar reflectance Index (SRI) is another metric for comparing the “coolness” of roof surfaces1. It and the clean white roof has a solar reflectance of 0.80 and thermal emittance of 0.90. . one or more layers of plastic or rubber material with.
11 Sep 2016 CAD RETEC®2016 : The 54rd Annual Society of plastics Engineers Color and Appearance One way to measure the energy absorbed by any substrate is by determining its Total solar reflectance (TSR), expressed as a
solar radiation is the naturally occurring radiation that reaches the earth's surface. It includes visible light as well as ultraviolet and infrared light (Graph 1). The visible band of the electromagnetic spectrum, which is the only range that can be

Tests show that, compared to ordinary TiO2, the spectra of ALTIRIS<sup>®</sup> W400 pigment can boost the solar reflectance of white and light colored plastics by as much as 25%. This in turn can enhance the thermal stability, weather resistance and
reflectance, or albedo, is the percentage of solar energy reflected by a surface; the higher the percentage, the more energy . (There are several PVC plastics running at the higher end of the range, with one PVC plastic's albedo as high as 86
Plastic foils containing nonabsorbing pigments can display a high reflectance of solar radiation combined with a high transmittance in the atmospheric window region in the thermal infrared. Such foils can be applied as selective covers
15 Feb 2018 Supporting this innovative service is a new spectrophotometer capable of reading solar reflectance in the NIR spectrum. It enables therefore, the measurement of solar reflectance levels of colourants to ensure that specified

Reflectivity is an optical property of material, which describes how much light is reflected from the material in relation to an Reflectivity depends on the wavelength of light, direction of the incident and reflected light, polarization of light, type of the material (metal, plastic, etc.) solar: Average of reflectivity values of all wavelengths with the weight of the intensity of solar radiation at a given wavelength.
29 Oct 2014 The light reflectance value of paints and coatings correlates directly with the urban heat-island effect. The ability to measure the reflective qualities of these products can help identify their solar absorption rate. Defensive Measures: UV Analysis of Sun Protection in Fabrics and Detergents.
