Abstract
Conventionally Toluene diisocyanate (TDI) and Isophorone diisocyanate (IPDI) are used as curatives for HTPB to form crosslinked urethane networks. Urethane formation is a fairly rapid reaction with TDI. Since this limits the useful pot life of the propellant, lesser reactive IPDI is more suitable in propellant formulations where a high pot life of the propellant paste is needed for processing big size grains. The aliphatic nature of IPDI makes it slow reactive, thus yielding a longer pot-life and penetrometric pot life which are the favorable factors for processing large boosters [1-3]. IPDI is also less toxic and hence used by many manufacturers. One disadvantage is that its longer cure time. In this paper, a detailed study was made on the HTPB-IPDI propellant behaviour and also a comparative study was made with HTPB-TDI propellant system to understand the viscous and mechanical behaviour of the propellant system by its process parameters and cure catalysis system for HTPB-IPDI system.
