Weather-Induced Degradation Study of Polystyrene Using the Photoprobe

This application note presents reproducibility study on a rapid, automated polymer degradation setup that introduces user-settable ultraviolet (UV) light, reactant gas and controlled temperature in a closed system.

Introductions

Environmental conditions play a critical role on polymer lifetime, and traditional degradation study takes time ranging from hours to days due to limited light intensity. CDS’s Photoprobe is using free-space focusing technology and improves the light intensity to 800 mW/mm² from 260 nm to 400 nm wavelength, which reduces the time on weather-induced degradation study down to minutes.
