The data reported in the “technical features/technical data sheets” refer to samples obtained in the perpendicular plane to the growth direction of the product during the reaction phase and not near the external surfaces. High resilience materials such as HR and AT must be previously subjected to mechanical treatments to generate cell breakage (mangling).
We recommend to obtain the desired details so that during the final use phase they are stressed in a parallel direction to the direction of growth.

In case of compressed materials it will be necessary a waiting time of at least 24 hours from the material decompression. The material must be kept compressed for the shortest possible time, ideally just for the time necessary for transport. In the 24 hours following decompression (or at least for a few hours) it is necessary that the blocks/plates are not subjected to pressure from any direction, such as load compression, blocks / plates stacked on one another or pressed against the wall. For viscoelastic materials it is necessary to consider their thermo sensitivity: the ideal temperatures should be higher than 15 degrees. It is also necessary that the support base is sufficiently smooth to allow the material to “slip”, thus facilitating the return.
