The flexible foams also show a ratio E'-100°C /E'+25°C of 1.3 to 15.0, preferably of 1.5. to 10 and most preferably of 1.5 to 7.5. The tan-- max over the -100°C to +25°C temperature range is below 0.2. The core density of such foams may range from 4-30 kg/m3 and preferably ranges from 4 to 20 kg/m3 (measured according to ISO 845). By the heat treatment the density increase caused by the crushing is reduced; often the density increase due to the crushing is limited to less than 10% for foams which have been treated.
