Ballistic Modifiers

essential to propellant performance

Shepherd Chemical is a leading manufacturer of ballistic modifiers, or “burn rate modifier” (BRM) additives, used in extruded double based (EDB) propellants for fuel rockets. These compounds are typically manufactured with lead and copper materials. Metal based compounds are essential to propellant performance, enabling continuous, even, and controlled burn. Shepherd’s ballistic modifier innovations include lead-free bismuth alternatives that are both low-toxic and environmentally friendly. We manufacture to military specifications and have expertise in export licensing that supports the supply of these critical materials.
