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.
