EPX-2R is a high-performance plastic explosive produced for different applications. EPX-2R is based on RDX (1,3,5-trinitro-1,3,5-triazinane) bonded by the elastic matrix of the softened styrene butadiene binder. A computerizing mixer plastograph was used for the production of EPX-2R. The internal energy of combustion was measured and used to determine the enthalpy of formation. Friction and impact sensitivities were measured. The velocity of detonation was determined experimentally, and the detonation properties were calculated by the EXPLO 5 code. For comparison, traditional plastic explosives, composition C-4, Semtex 10, Formex P1, EPX-1, and Sprängdeg m/46, were studied. It was concluded that the velocity of detonation of EPX-2R was higher than the studied samples except composition C-4, while its sensitivity is the lowest. Interesting inversely proportional relationship between the measured internal energy of combustion and the calculated heat of detonation was observed.

与传统类型比较的新型高性能塑料炸药的制备与表征

EPX-2R是为不同应用生产的高性能塑料炸药。EPX-2R基于RDX（1,3,5-三硝基-1,3,5-三嗪烷），通过软化的苯乙烯丁二烯粘合剂的弹性基质粘结。使用计算机化的混合式增塑机来生产EPX-2R。测量燃烧的内能，并将其用于确定形成的焓。测量了摩擦和冲击敏感性。实验确定了爆炸速度，并通过EXPLO 5代码计算了爆炸特性。为了进行比较，研究了组成为C-4，Semtex 10，Formex P1，EPX-1和Sprängdegm / 46的传统塑料炸药。结论是，除组成C-4外，EPX-2R的爆轰速度高于研究样品，而其敏感性最低。
