← ScienceWhich outcome happens when polyurethane foam degrades due to hydrolysis?
A)Weakened structural integrity develops✓
B)Increased thermal insulation occurs
C)Enhanced chemical resistance emerges
D)Improved sound absorption appears
💡 Explanation
Hydrolysis breaks the ester bonds in polyurethane, causing bond scission and therefore weakened structural integrity, rather than improving insulation; this is due to the chemical breakdown, not a change in pore structure.
