Unique fire retardant properties. UltraCarb has a unique 3-stage fire-retardant mechanism. Whereas the classical endothermic flame retardant fillers act by releasing water in a single action process, our premium product works as follows: Water is released at temperatures of ~220°C (thermal decomposition) CO 2 release at temperatures of ~330°C.

Abstract. Selected metal hydroxides are effective flame retardant fillers with strong green credentials and comprise about 40% by weight of the total polymer flame retardant market. Their fire retardancy is primarily a result of a strongly endothermic decomposition with the release of water. As a consequence of this mechanism, they do …
