Composite solid propellants based on hydroxyl terminated poly butadiene (HTPB) have become the workhorse propellants in the present-day solid rocket motors world-wide. Sufficiently long pot life for the propellant paste is a favorable condition to enhance the ease of processability and thereby to manufacture defect-free propellant grains. A study on the effect of isomer ratio of toluene diisocyanate (TDI) on a mixture of polymer and curative in the processing of rocket propellants was reported. Viscosity build-up of a HTPB–TDI propellant slurry was measured using a Brookfield viscometer. Viscosity build-up of propellant slurry at a constant temperature affected remarkably by the isomer ratio of TDI. The pot-life of the propellant slurry using Type-B TDI was found as 5 hrs. in comparison to 4 hrs. on using the Type-A TDI as curative. The viscosity buildup data of the HTPB–TDI system showed a power function (allometric function) with time. The mechanical behavior of the propellant was not affected by the isomer ratio of TDI.
