PLASTIC PROPELLANT - THE EFFECT OF COMPOSITION ON SLUMP RESISTANCE: PART 1: SUMMARY OF WORK TO JUNE, 1964

Abstract

This memorandum summarises existing information concerning the effect of composition on the tendency of large charges of plastic propellant to deform, or slump under their own weight. Studies of the current type of formulation have indicated that further improvements in slump resistance are possible as the result of changes in solids content, particle size, or binder viscosity. Brief investigations of the use of polymerisably polyester plasticisers and a modified 'plastisol' process have given encouraging results. These and other means of modifying the binder will be further investigated. Present evidence suggests that an increase in tensile strength of 100 to 200% is feasible, but this may be accompanied by some loss of extensibility.
