propellants definition

propellants means substances or mixtures that react chemically to produce large volumes of hot gases at controlled rates to perform mechanical work;
propellants means compressed gases or vapours in a container which, upon release of pressure and expansion through a valve, carry another substance from the container. Typical propellants are carbon dioxide, propane, butane, and isobutane;
propellants means gases other than air which expel a foodstuff from a container;

More Definitions of propellants

propellants as follows: 1. Any solid "propellant" with a theoretical specific impulse (under standard conditions) of more than: a. 240 seconds for non-metallized, non-halogenized "propellant"; b. 250 seconds for non-metallized, halogenized "propellant"; or c. 260 seconds for metallized "propellant";
propellants not specified elsewhere in the Munitions List, specially designed for military use; c. Pyrotechnics", fuels and related substances, as follows, and mixtures thereof: 1. Aircraft fuels specially formulated for military purposes; c.1. are finished products, not their constituents. 2. ▇▇▇▇▇ (aluminium hydride) (CAS 7784-21-6); 3. Carboranes; decaborane (CAS 17702-41-9); pentaboranes (CAS ▇▇▇▇▇-▇▇-▇ and 18433-84-6) and their derivatives; 4. Hydrazine and derivatives, as follows (see also ML8.d.8. and d.9. for oxidising hydrazine derivatives): a. Hydrazine (CAS 302-01-2) in concentrations of 70% or more; b. Monomethyl hydrazine (CAS 60-34-4); c. Symmetrical dimethyl hydrazine (CAS 540-73-8); d. Unsymmetrical dimethyl hydrazine (CAS 57-14-7); c.4.a. does not apply to hydrazine 'mixtures' specially formulated for corrosion control.
