Product Name:Octavinyl-POSS
English Name:Octavinyl-POSS
CAS No.:69655-76-1
Aliases:Octavinyl cage silsesquioxane, Vinyl POSS, OV-POSS
Molecular Formula:C16H24O12Si8
Physical Properties:White powder, melting point greater than 300°C, density approximately 1.16 g/cm³. Insoluble in water, soluble in organic solvents such as tetrahydrofuran and toluene. The stable cage structure and eight vinyl functional groups provide high reactivity for further polymerization or crosslinking reactions.
Uses:Used as an organosilicon nano-additive for preparing organic-inorganic hybrid materials. The vinyl groups can participate in free-radical polymerization and hydrosilylation reactions, serving to modify resins, rubbers, and coatings to improve heat resistance, mechanical strength, and dielectric performance. It is also used as a crosslinking agent in polymer nanocomposites.
Technical Specifications:
Purity: 97%
Appearance: white powder
Molecular weight: approximately 947.34 g/mol
Storage: keep in a dry, cool, well-ventilated place in a tightly closed container with proper labeling.
