Hydrolytic degradation Estane® binder with

The experimental data for molecular weight and L/Lo agree well with the hydrolytic degradation predictive model for Estane as shown in Figure 10. Ongoing experimental work validating the Estane hydrolysis model for Estane binder will contribute to providing a robust lifetime prediction for PBX 9501 explosives. 

The potential value of the NMR MOUSE for detecting hydrolytic degradation in Estane was demonstrated. This technique is sensitive to increased chain mobility in the degraded Estane and showed a good correlation of the relaxation time with a decrease in molecular weight. Additional studies of aged Estane/NP/Irganox binder are underway to evaluate use of this instrument.
