Diphenyl tetrasiloxane IOTA 234 is a high-quality silicone-based functional material that plays a vital role in the fields of silicone rubber, silicone resin, and related applications. Its chemical name is 3,5-Bis(dimethylsiloxy)-1,1,7,7-tetramethyl-3,5-diphenyl-tetrasiloxane, with an alias of 1,1,3,3-tetra(dimethylsiloxy)-1,3-diphenylsiloxane and a CAS number of 66817-59-2. This product boasts a regular chemical structure and stable physical-chemical properties. It appears as a colorless and clear liquid, facilitating mixing and processing in various production processes. Its key specifications are outstanding: the specific gravity is 1.005, the refractive index at 20℃ is 1.4622, the boiling point is 95-96°C under 0.25mmHg, and the flash point (COC standard) exceeds 110℃. The purity, tested by Gas Chromatography (GC), is not less than 95%, ensuring stability and reliability during application. In terms of miscibility, Diphenyl tetrasiloxane IOTA 234 exhibits excellent compatibility with various silicone-based materials such as dimethyl siloxane, liquid silicone rubber, phenyl silicone rubber, and phenyl resin, without undesirable phenomena like stratification or precipitation. Leveraging this advantage, it is widely used as a crosslinker for addition-cure silicone rubber, phenyl silicone rubber, and phenyl resin. It plays a crucial role in material molding and performance optimization, helping related products form stable structures and excellent service properties.
