What is the softening temperature of PU foam?

The softening temperature of polyurethane (PU) foam typically ranges from about 70°C to 100°C (158°F to 212°F), depending on the specific formulation and density of the foam. At this temperature, the foam begins to lose its structural integrity and can become more pliable. It's important to note that different types of PU foams may have varying thermal properties, so the exact softening temperature can differ.
