To study the effects of the binding agents on the burning rate of the tungsten delay composition, two delay compositions in bound form were made with nitrocellulose and Teflon separately. An experiment on the two delay compositions was carried out and their delay time at room temperature and high temperatures(120, 160, 180 ℃) were obtained. The results show that the burning rate of the composition with nitrocellulose as binding agent is much faster than that of the composition with Teflon as binding agent. When the temperature rises, the burning rate of the composition with nitrocellulose as binding agent increase rapidly while the burning rate of the composition with Teflon as binding agent does slowly.
