Product Introduction
Product Description:
SF-202 is a highly efficient, environmentally friendly inorganic flame-retardant synergist with
excellent char-forming capability. It can be used either independently or in combination with
other flame retardants to achieve ideal char formation and smoke suppression performance. In addition, it provides reliable thermal stability with a high decomposition temperature.
Its mono-dispersed structure ensures good processability and meets the dispersion requirements of various polymer systems.
Product Features:
1. Mono-dispersed, enabling significantly improved dispersion in polymer matrices.
2. Low dosage requirement—an addition level of 1.5% can effectively enhance char formation
