  2. Application: Ammonium nitrate dedicated bonding agent. The hydroxyl of the molecular structure enters the crosslinking network through bonding in chemical with HTPB, and physical absorption has happened between much nitrile groups and ammonium nitrate oxidant. Ammonium nitrate or modified for HTPB solid propellant has been used to improve the mechanical property. It has been also used to be the bonding agent to improve the mechanical property for HTPB and AP solid propellant.                                         Solid Propellant                              Improve  mechanical properties of rubber products                         Improve rubber aging resistance                                                            Crosslinker                                                                        Bonding agent                                                          HTPB Propellant                                                                                                        Rocket 3.
