Influence of Adhesives to Mg/PTFE Pyrotechnical Composition Performances

To find out the influence of adhesives to Mg/PTFE pyrotechnic composition, 12 materials such as fluororubber, phenolic resin, etc as the adhesives component of pyrotechnic composition, and which burning speeds were measured by high-speed camera, and by the way, which burning temperatures were checked by infrared thermometer. In addition, the friction and impact sensitivities of compositions had been compared. The experiment results show that the Mg/PTFE pyrotechnic composition with adhesive of phenolic resin has the best performance, which burning temperature is 1268.4 °C, linear burning speed is 6.46 mm·s-1, mass burning speed is 3.06 g·㎝-2·s-1.
