Visualization of multi-factor changes in HTV silicone rubber in response to environmental exposures

In this paper, we present a tool for visualizing multi-factor changes in HTV silicone rubber using results from ATR-FTIR, color coordinates, contact angle, and voltage breakdown test. Experimental works were performed on samples collected from a 22 KV silicone rubber insulator. The specimens were subjected to accelerated degradation using an Accelerated Weathering Tester (QUV). The proposed 3D scatter plot based on the obtained data shows a clear trajectory on how a new specimen degrades over time and eventually leads to complete failure. In addition, the application of Multiple Linear Regression method provides linear plane equation which quantitatively describes the changes in silicone rubber in response to environmental exposures over time.
