Zusammenfassung:Figure 1 presents data generated during experiments to measure the stress-optical coefficient in Tritan. The stress-optical coefficient enables evaluation of residual stress levels in molded parts based on comparison of birefringence within the parts, a common tool for assessing part quality. The stress-optical coefficient for Tritan is significantly higher than for polycarbonate (164 vs. 97.2). However, the coefficient is inversely related to residual stress level.
