"Understanding Temperature Effects and Acceleration in Natural and Laboratory Weathering Tests: Polymers are known to be highly sensitive to UV and temperature. Temperature plays a role in color change, cracking, gloss loss, deformation, blistering, and a wide range of other failure profiles. Understanding how light and temperature interact with each other can give researchers insight into acceleration factors, and why test results can differ for similar materials. In this presentation we will characterize natural sunlight and temperature stresses found in nature. We will investigate how visible and IR energy from sunlight accelerate photo chemical degradation caused by UV energy. We will discuss how color, texture, thickness, angle, and other variables contribute to unique surface temperatures, which influence the speed of material degradation. Finally, we will share techniques and technological innovations that help researchers obtain precise understanding of material temperatures in weathering test devices."
