Anhui IOTA Silicone Oil Co., Ltd. introduces IOTA 9502 Vinyl POSS (Octavinyloctasilsesquioxane), redefining the performance limits of polymer materials with its unique cage-like structure and exceptional heat-resistant and flame-retardant properties. This white powdered nanomaterial significantly enhances the heat resistance and flame retardancy of polymers such as epoxy resins and polyurethanes through crosslinking modification and nanocomposite methods, providing breakthrough solutions for aerospace, electronics, electrical, and other fields.
Cage-like Molecular Structure: Unique Si-O-Si inorganic framework with excellent thermal stability
Dual Functionality: Simultaneously improves heat resistance and flame retardancy of matrix materials
Nano Effects: Controllable particle size, uniform dispersion in the matrix
Reactivity: Vinyl functional groups participate in polymerization reactions, achieving molecular-level compounding
✓ Aerospace Materials: Increases heat resistance temperature of epoxy resins by over 80°C
✓ Electronic Packaging Materials: Achieves UL94 V-0 flame retardancy rating without compromising mechanical properties
✓ High-Performance Coatings: Heat resistance temperature elevated to above 400°C with outstanding oxidation resistance
✓ Specialty Rubbers: Significantly improves flame retardancy while maintaining elasticity
"Traditional flame retardants often sacrifice mechanical properties, while IOTA 9502 achieves a perfect balance between flame retardancy and enhancement," stated IOTA's Technical Director. "Its nanoscale dispersion ensures uniformity and stability of material properties."
