Which outcome happens when polyurethane foam degrades due to hydrolysis?

💡 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.
