There is a continuing effort at Lawrence Livermore National Laboratory to formulate new plastic-bonded explosives (PBX) with enhanced energy and improved safety characteristics. We have found that these parameters depend mainly upon the polymer or plastic chosen as binder. Typically, these materials have 5 to 10 vol % polymer and the explosive may be treated as a solid coated with a polymeric film. In an effort to determine which properties of a polymer are advantageous here, we have examined in depth three polymers (Kel-F 800, Phenoxy PKHJ, and Kraton G 1650) and an insensitive explosive (1,3,5-triamino-2,4,6-trinitrobenzene (TATB)). We determined mechanical and rheological properties, surface characteristics, and acid-base behavior of the pure materials and composites (PBX). It was found that extensibility, glass transition temperature, and Lewis acidity surface wettability of the components of a PBX are governing factors in safety characteristics. 7 tables.
