Thermal aging of HTPB/IPDI-based polyurethane as a function of NCO/OH ratio

Thermal aging of HTPB/IPDI-based polyurethane as a function of NCO/OH ratio

Thermal aging of hydroxy-terminated polybutadiene/isophorone diisocyanate (HTPB/IPDI)-based polyurethane was studied as a function of NCO/OH ratio (1.0 and 0.85). Samples were aged in air ovens at 50, 60, 65, and 70 ºC for periods of time from 1 to 34 weeks. Changes in chemical (swelling testing and...
