What Is Hipel 710
Referring to the trade name for a hydroxyl-terminated polybutidiene (HTPB) propellant, comprising 84% ammonium perchlorate (NH4 ClO4) (oxidizer), 9.1% HTPB (fuel), 0.7% aluminum trihydrate (Al2 O3 x3H2 O) (burn rate catalyst), 0.2% Fe2 O3 (burn rate stabilizer), and 6% polymide (Kermid 601). This is a readily ignitable propellant mixture. The mixture is sensitive to ignition by flame, heat, friction, impact or electrostatic discharge. When ignited, the mixture burns producing heat, flame, hot gases and hot particles. It offers a long shelf life and high stability. Since it is a simple composite propellant, it has less volatile contaminants than other available gun propellants.
