In the flame retardant modification of engineering plastics, coatings, and specialty polymer materials, traditional halogenated flame retardants are facing increasing environmental pressure. IOTA 6108 Phenyl Cage-Type Silsesquioxane contains no fluorine, chlorine, bromine, or other halogens – it is an absolutely eco-friendly, halogen-free flame retardant. It can also be used as a synergistic flame retardant additive and a powder coating defoamer, providing a green, efficient flame retardancy and processing aid solution for PC, PA, epoxy resins, and other materials.
IOTA 6108 is a phenyl cage-type silsesquioxane with high phenyl content and a stable cage molecular structure. It exhibits excellent synergistic flame retardancy, a high refractive index, and good transparency, and is widely used in the synthesis of high-performance silicone materials and specialty additive systems.
