Organosilicone Compounds - Tetraphenylsilane Fully Tetra-Aromatic Silicon Core Organosilicon Compounds for Ultra-High-Temperature Heat-Resistant Silicone Matrix & Low-Dielectric High-Refractive Composite Materials 1. Product Overview This tetraphenylsilane Organosilicone Compounds is high-melting white crystalline solid with melting point 230–234 ℃, fully composed of four rigid phenyl aromatic rings bonded to central silicon atom, without any hydrolyzable alkoxy, Si-H hydride, vinyl or ester functional groups. It has excellent miscibility with Silane Coupling Agents, Silicone Resins and Siloxane Polymers, acting as inert high-temperature rigid reinforcing filler monomer for ultra-high-temperature aerospace silicone matrix composites, low-dielectric high-refractive electronic packaging silicone materials and ablation-resistant thermal barrier coating systems. When blended with aromatic functional Silane Coupling Agents, it builds all-aromatic rigid crosslink skeleton to drastically…
