Polyurethane Binder Systems for Polymer Bonded Explosives

摘要

Polymer bonded explosives (PBXs) consist of explosive components bound together by a polymeric binder. The most common binder systems in current PBXs are polyurethane based and contain plasticisers and other chemicals that alter processability, mechanical properties and chemical stability. This report details the history of PBX binders, components of polyurethane binder systems, their properties and the procedures for obtaining the ingredients, as well as the basics of formulation, testing and quality control. Also included are details of PBX formulations on which research has been undertaken at DSTO.
