L'incorporation de composé silane a considérablement amélioré la vitesse de combustion de la composition et la résistance mécanique des moulages de la composition. Cette composition pour générateur de gaz convient pour remédier aux défauts des compositions de générateurs de gaz d'airbags conventionnels qui ne font pas preuve d'une vitesse de combustion satisfaisante et ne font pas preuve d'une résistance mécanique suffisante une fois moulées, tout en conservant leurs avantages connus, à savoir leur faible sensibilité et leur capacité de production d'une quantité suffisante de gaz.
