Isothermal aging effects on extex-tetryl mixtures. Progress report, October 1971--December 1971

An isothermal aging study of a 50/50 weight mixture of Extex (80% PETN, 20% Sylgard) and Tetryl (2,4,6-trinitrophenylmethylnitramine) was undertaken to determine its stability at elevated storage temperatures (60 and 100 C) for extended periods (100 days), to simulate long storage. The original components and mixture, along with the isothermal residues underwent various analyses including infrared spectral and differential thermal analyses, weight loss monitoring at selected intervals up to 100 days, and photomicrography
