Síntese de poliuretanos modificados por óleo de mamona empregados em materiais energéticos
Química Nova, 2013 The aim of this work was to synthesize a polyurethane polymer matrix using castor oil as a polymer chain modifier, whose characteristics can be adjusted for use as a binder in the manufacture of energetic materials such as propellant and pyrotechnics for

Thermodynamic Scaling of the Viscosity of Van Der Waals, H-Bonded, and Ionic Liquids
, 2006 Viscosities and their temperature, T, and volume, V, dependences are reported for 7 molecular liquids and polymers. In combination with literature viscosity data for 5 other liquids, we show that the superpositioning of relaxation times for various glass-

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 11-12, Page 32-39, December 2025.ABSTRACT The balance between performance and safety of high explosives is at the heart of the current studies, and new ways of combining safety and performance have hence been elaborated. This study focuses on a mixture of 3‐nitro‐1,2,4‐triazol‐5‐one (NTO) and octogen (high melting explosive [HMX]).

Preliminary research of composite rocket propellants with hexogen and titanium oxide powder [PDF]
Scientific Technical Review, 2018 Composite solid propellants based on ammonium perchlorate/hydroxyl-terminated polybutadiene/isophorone dyisocyanate including two levels of hexogen (RDX) are presented in this paper. The mass of RDX increased in relation to oxidant, with constant bimodal

Elucidation of the dynamics for hot-spot initiation at nonuniform interfaces of highly shocked materials [PDF]
, 2011 The fundamental processes in shock-induced instabilities of materials remain obscure, particularly for detonation of energetic materials. We simulated these processes at the atomic scale on a realistic model of a polymer-bonded explosive (3,695,375 atoms/
