In the preparation systems of addition-cure silicone rubber and phenyl silicon-based materials, IOTA-231 hydrogen-terminated phenyl silicone oil (including hydrogen phenyl silicone oil) stands out as a critical crosslinking core that determines product performance due to its unique molecular structure and excellent compatibility. As a hydrogen-terminated linear phenyl silicone oil, its precise molecular weight range of 333–1000 provides stable reaction activity and broad adaptability, offering a solid foundation for the synthesis of high-end silicon-based materials.
Stable and uniform physicochemical properties form the basis for reliable application. IOTA-231 appears as a colorless, transparent viscous liquid, visually pure and free of impurities, allowing precise integration into various silicon-based material systems. Authoritative testing shows its core indicators are outstanding: density is stable at 0.99–1.00, refractive index at 20°C is 1.50–1.51, and physical properties are uniform and controllable. The viscosity at 25°C is only 1–10 mm²/s, providing excellent flowability for accurate measurement and uniform dispersion during production. Notably, its flash point is >110°C, ensuring excellent operational safety, while the hydrogen content of 0.20–0.60% provides sufficient reactive sites for crosslinking, ensuring efficient and complete reactions.
Its excellent compatibility and crosslinking performance establish its irreplaceable core value. IOTA-231 exhibits good miscibility with mainstream silicon-based materials such as methyl silicone oil, liquid silicone rubber, phenyl silicone rubber, and phenyl silicone resin. It can achieve uniform mixing without additional compatibilizers, significantly simplifying production processes. In key applications, it serves as a dedicated crosslinker for addition-cure silicone rubber, phenyl silicone rubber, and phenyl silicone resin. Through precise crosslinking reactions, it enhances the material’s mechanical properties, high-temperature resistance, and stability, playing a central role in both elastomer elasticity control and resin film formation optimization.
From production adaptation to storage and transportation, product design reflects thoughtful attention to detail. Packaging is available in 15 kg and 200 kg coated steel drums, flexibly meeting the needs of laboratory research and industrial-scale production. Storage requires only a ventilated, cool place without special harsh conditions, reducing warehouse costs. Whether producing high-end silicone rubber products or developing specialty phenyl silicone resins, choosing IOTA-231 hydrogen-terminated phenyl silicone oil means selecting high-efficiency crosslinking, broad material compatibility, and stable product quality, providing core driving power for the upgrading of the silicon-based materials industry.
