The paper deals with a new composite propellant specially developed for use in micro gas generators for automotive safety equipments like seat belt retractors or pretensioners. The Micro Gas Generator Composite 'MGC' developed by Autoliv uses a first generation 'green' composite propellant (non-nitrocellulose). This product was designed to respond to the increasing demand for pyrotechnical buckle pretensioners and roto retractor pretensioners in cars and to fulfil worldwide specifications. The main benefits are: well-known technology, environmental friendly raw materials, fully recyclable, safe manufacturing handling, safe and non toxic handling, low % of non-toxic ashes, a continuous production process. MGC propellant is a mixture of about 80 % filler and 20 % thermoset binder with additives. This composite propellant in its specific grain shape is extruded by a continuous process using a twin screw extruder. The main advantages of the propellant are: no toxic gases, high thermal stability, reproducibility of ballistic performances thanks to the use of well defined grain shape and composition.
