Abstract: The methods of improving the properties of the insulator of gas generator were presented and analysised.The effects of the procesess on the properties of the insulator were investigated.The different kinds of insulators which meet the requirements of gas generator completely were given:the EPDM insulator containing asbestos,the NBR insulator containing asbestos and the EPDM insulator containing polyaramide.

Key words: Gas generator;Heat insulator layer;Inhibitor;Ablation property
