  • Applications

    Propylene glycol dinitrate (CAS 6423-43-4) is an energetic nitrate ester used primarily as a plasticizer in nitrocellulose-based propellants and as a key component of double-base propellants, improving flexibility and burn performance. It also serves as a processing aid and stabilizer in energetic formulations, helping to control viscosity and processing during manufacture. In pyrotechnic compositions and propulsion-related applications, it is employed in rocket propellants, small-arms propellants, and certain flare or tracer formulations. It may be encountered as an energetic additive that contributes to overall energy content within propulsion and pyrotechnic systems.
