Is the foamed silicone product the softer the smaller the density?

Foamed silicone products important properties. At present, the market mainstream density is between 0.3g/cm3 and 0.9g/cm3. Here, we should be clear about a concept, that is, "closed cell foam" and "open cell foam". Small hole foam: The foam density is uniform, but the foam hardness is relatively hard. On the contrary, large-cell foaming: the foam density is rough, the foam hardness is soft, the two are completely different, there is no good and bad between the two, see where the specific product is used, choose the right product. In theory, foamed silicone products are the smaller the foam density, the softer, and there is a hardness of rubber, which will affect the hardness of foamed silicone products.
