Mechanical properties of HTPB-IPDI-based elastomers
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.

A highly stretchable and self-healing hydroxy-terminated polybutadiene elastomer
The damage such as microcracks limits the application of hydroxy-terminated polybutadiene (HTPB) elastomer. Here, hydroxy-carboxy-terminated polybutadiene (HCTPB) and Fe3+ selected to facilitate ionic bonds (COO−⋯Fe3+) formation is proposed as a ...
