The cutting suitability is characterized, that you can cut these without danger. That’s means that they are not produce toxic smoke or start to burn. Further more a suitable material must you can cut fast, so that the working time is as short as possible. This is a parameter of the nominal density. If the nominal density is high so the foam is cut very slowly. The stuff must keep a smooth surface. It is necessary that the foam don’t stick together ore make threads. Furthermore the foam have not change colour, because the packing is also the promotion for the product.
From the packing suitability materials the follow show this characteristic:
