The addition-cure silicone rubber market has experienced rapid growth in recent years, with widespread applications in food molds, baby products, medical consumables, and electronic packaging. Tetramethyltetravinylcyclotetrasiloxane (IOTA V4), as a crucial additive (intermediate), plays an irreplaceable role in improving the processing performance and final physical properties of silicone rubber.

The crosslinking reaction of addition-cure silicone rubber relies on organosilicon monomers with stable vinyl content. IOTA V4, with its four uniformly distributed vinyl groups, exhibits faster reaction rates and higher conversion rates in platinum-catalyzed reactions. Its high purity (≥90%) ensures product stability during production, reduces the risk of deactivation due to impurities, and results in silicone rubber products with higher tensile strength, tear strength, and a better feel.

Research data shows that the addition of appropriate amounts of IOTA V4 to addition-cure silicone rubber significantly improves the material's flexibility, resistance to yellowing, and long-term stability. Its low shrinkage due to its chemical structure is also highly recognized by mold manufacturers and high-precision component manufacturers. As market demands for the performance of food-grade and medical-grade silicone rubber continue to increase, the application value of IOTA V4 will become even more prominent.
