1- Double base rocket propellant, Tubular grains, is a kind of double base propellant containing Nitrocellulose (NC), Nitroglycerine (NG), Dinitrotuloene (DNT),Burning rate catalyst, Centralite and wax. It can be produced by solventless extrusion process. 2- Double base Strip propellant is a kind of double base propellant containing Nitrocellulose (NC), Nitroglycerine (NG), plasticizer and Stabilizer. Application: 1- Double base tubular grain is used as flight propellant in SPG-9 rocket family. 2- Double base strip type propellant is used as start ignition charges for SPG-9 rocket family. Storage: should be stord in -10°C up to +30°C Shelf life: 15 years (min)
