Liquid silicone rubber (LSR) is widely used in the medical, electronics, and consumer goods industries due to its excellent processing performance and environmentally friendly properties. In LSR systems, the choice of crosslinking agent is crucial. IOTA 232, a high-purity (≥98%) hydrogen-containing siloxane, not only possesses stable reactivity but also achieves uniform distribution within the system, thereby improving the consistency of the crosslinking reaction. Its phenyl structure further enhances the material's heat resistance and optical stability, making it particularly suitable for applications with high performance requirements. Furthermore, its high flash point and stable physicochemical properties provide better safety and reliability during production and use. As the applications of LSR continue to expand, the value of this type of high-performance crosslinking monomer will become increasingly prominent.
