The core value of IOTA-233 Hydrogen-Terminated Phenyl Polysiloxane lies in its deliberately engineered T-type molecular structure. This architecture imparts branched characteristics that differ from linear silicone oils, enabling it to offer a greater number of crosslinking sites when functioning as a crosslinker. Its molecular weight distribution, spanning from 550 to 3000, has been considered to balance the high reactivity associated with lower molecular weights and the good film-forming and mechanical strength properties linked to higher molecular weights. The active hydrogen content (H%) is maintained within a controllable range of 0.35% to 0.75%, allowing formulators to flexibly adjust the addition ratio based on the desired performance of the target product, thus achieving fine-tuned control over crosslink density and final product hardness. A Key Component for Enhancing Overall Material Performance Within phenyl silicone rubber and silicone resin systems, IOTA-233 plays a pivotal role as a key component. The introduction of phenyl groups inherently provides materials with good high- and low-temperature resistance as well as radiation resistance. As a crosslinker, IOTA-233 further reinforces these performance advantages. The crosslinked network it helps form aids the material in maintaining structural integrity under high-temperature conditions, reducing performance degradation caused by thermal aging. Simultaneously, its good compatibility with base polymers like methyl silicone oil and liquid silicone rubber ensures uniform crosslinking reactions, preventing issues of localized under- or over-crosslinking, which ultimately enhances the overall reliability and service life of the finished goods.
