* measured on a test sample of 6 x 6 x 3 cm size with two parallel undamaged surfaces, cut out of a honeycomb.

** The softening point represents the temperature at which the material starts to slump down.

*** Measured according to DIN EN 993-16: The sample with a defined surface is being exposed to HCl for a certain period. The figures represent the mass loss (as lower this figure is as better is the resistance).
