Sundow has ATO Substitute
Dec 17, 2025
The SD-100 series product is a powdered low antimony trioxide (ATO) blend that can replace one-to-one pure ATO in many formulations. Besides ATO, it is composed by other different flame retardants and synergists, such as metal oxides, smoke suppressants, stabilizers, and other additives, which allow to reduce ATO content without affecting negatively its performance.
We provide various SD-100 by controlling the production process, achieving one-to-one replacement of flame-retardant ATO in different applications.
