With the continued increase in global demand for high-performance silicon materials, tetramethyltetravinylcyclotetrasiloxane (IOTA V4) is gradually becoming one of the core raw materials of interest to silicone rubber and silicone oil manufacturers. As a cyclic siloxane with high vinyl reactivity and strong structural stability, IOTA V4 plays a crucial role in the production systems of high-vinyl silicone oils, liquid silicone rubber (LSR), addition-cure silicone rubber, and vinyl hydroxyl silicone oils.

Industry experts point out that silicone rubber products are developing towards higher added value, higher weather resistance, and higher adhesion performance. Achieving these properties relies heavily on the assistance of highly reactive vinyl monomers. IOTA V4 possesses advantages such as high vinyl content (≥29.8%), high purity (≥90%), and good controllability of reactivity, which can significantly improve the crosslinking density and mechanical properties of silicone systems, resulting in stable performance in terms of transparency, elasticity, and resistance to yellowing in the final product.

Meanwhile, as a crucial intermediate in the production of high-vinyl silicone rubber, IOTA V4 improves flowability and accelerates cross-linking in addition-cure silicone systems, making it particularly suitable for the production of electronic potting materials, medical silicone products, food-contact silicone, and appliance seals.

As the silicone materials industry moves towards higher purity and higher added value, the market demand for IOTA V4 is maintaining rapid growth. Industry experts predict that its applications will gradually expand to multiple high-end sub-sectors such as functional silicone resins, specialty coatings, and high-transparency, high-strength silicone rubber, providing downstream manufacturers with a fundamental raw material for continuous innovation.
