Evonik factors in sustainability even when selecting raw materials. CALOSTAT® consists primarily of non-crystalline silicon dioxide that Evonik manufactures itself and has optimized for use as an insulating material.
The high-quality raw materials used completely eliminate the need for fungicides, algicides, pesticides, fire retardants, and binders. That’s good, because these substances are frequently toxic.
It goes without saying that Evonik pays very close attention to its supply chain, which is free of conflict resources. We have no reason to assume that CALOSTAT® could contain any of the materials identified in legislation such as the US Dodd-Frank Act or EU Regulation 2017/821. We source most of our silicon in Europe and do not compete with sources of construction sand.
