Solar material protection factor

Book topics include practical aspects of spectrometers and spectrometry, sample preparation, chemometrics, and calibration practices reflectance measurements and standard materials measurements. We have placed an emphasis on reflectance and color measurements due to their common usage in today s spectroscopic laboratories. Methods for selecting a measurement technique are included, as well as solar and color measurements. Spectrometry of new materials, ceramics, and textiles are covered by respective experts in their fields. An appendix of practical reference data for UV-VIS, NIR, IR bench top, IR microspectroscopy, and UV Sun Protection Factor (SPF) measurements is included. 

The present research shows the high aggressiveness on the polymeric material and articles and it specially shows the aggressive factors of the humid and tropical climate of Cuba on the robbers the different and more significative atmospheric factors, that is to say (temperature, solar radiation, ozone concentration) were supplied by the Institute de Meteorologia de la Repiiblica de Cuba (The Institute of Meteorology of the Republic of Cuba). The samples of the tested rubbers, especially elaborated with no antioxidant protections were made using the coded rubber, used by the Rubber enterprise Union with the number 471.
