Mechanical properties of HTPB-IPDI-based elastomers
Journal of Applied Polymer Science, 1997 A polyurethane elastomer having mechanical and adhesive properties suit- able for liner applications in solid rocket propellants was developed using HTPB as the prepolymer and IPDI as the curing agent. The effects of the NCO/OH ratio (R value) and the triol/diol ratio on the mechanical properties of the polyurethane matrix were investigated.

Burning Properties of Uncured HTPB Propellant
Journal of the Korean Society of Propulsion Engineers, 2016 ABSTRACT In this study, we examined the burning rate of the uncured pr opellant (with and without a curing agent application) in order to inspect the process of the HTPB solid propellant. The burning rate of the uncured propellant, that did not contain the curing agent, was approximately 9.7 mm/s at 1000 psi. In relation to the curing time, the burning
