Hydrolysis Resistance

PPS is a polymer which shows virtually no hydrolysis. Accordingly, Torelina™ features outstanding resistance to hydrolysis. Fig. C1 shows the decrease of elongation at break of various thin films when placed in saturated water vapor at 155°C. In absolutely dry conditions polyimide film boasts better thermal resistance than Torelina™. In water vapor, however, it deteriorates much more rapidly.
