Abstract
A pyrotechnic composition comprising: About 1 to 20% by weight of a thermoplastic resin selected from the group consisting of polyacetal resins, polyvinyl acetate resins and mixtures thereof; About 30 to 80% by weight of an alkali metal chlorite, such as sodium chlorite or potassium chlorite; and About 20 to 60% by weight of a coolant selected from the group consisting of calcium hydroxide, magnesium hydroxide or mixtures thereof. The invention also relates to a method of inflating an inflatable automobile safety restraint comprising the step of substantially completely inflating the restraint with the gaseous composition products of combustion of a composition comprising: About 1 to 20% by weight of a thermoplastic resin selected from the group consisting of polyacetal resins, polyvinyl acetate resins and mixtures thereof; About 30 to 80% by weight of an alkali metal chlorite, such as sodium chlorite or potassium chlorite; and About 20 to 60% by weight of a coolant selected from the group consisting of calcium hydroxide, magnesium hydroxide or mixtures thereof.
