Divinyltetramethyldisiloxane (CAS 2627-95-4) is a compound that may not be a household name, but its impact on the performance of silicone-based materials is profound. This colorless, transparent liquid is a cornerstone in many advanced manufacturing processes. NINGBO INNO PHARMCHEM CO.,LTD. provides this essential chemical and shares insights into its key properties and the significant benefits it offers to formulators and manufacturers.
The physical and chemical characteristics of Divinyltetramethyldisiloxane are critical to its functionality. With a low melting point of -99°C and a boiling point of 139°C, it remains stable across a wide temperature range, making it suitable for various processing conditions. Its density of 0.81 g/cm³ and refractive index of 1.411 further define its behavior. High purity, typically exceeding 99.0%, is a hallmark of the Divinyltetramethyldisiloxane supplied by NINGBO INNO PHARMCHEM CO.,LTD., ensuring reliability in demanding applications. When considering the purchase of Divinyltetramethyldisiloxane, these specifications are crucial for predicting its performance.
The primary application of Divinyltetramethyldisiloxane is its role as a linear inhibitor in two-part Silicone RTV-2 Addition Curing systems. In these systems, it acts as a retarder, effectively controlling the rate of the addition curing reaction. This control is vital for managing the pot life, allowing sufficient time for mixing, degassing, and application before the material begins to solidify. For manufacturers, this means better control over the manufacturing process, reduced waste, and improved product quality. The price of Divinyltetramethyldisiloxane reflects its crucial contribution to process efficiency.
Beyond inhibition, Divinyltetramethyldisiloxane is also utilized as a crosslinking agent. Its vinyl groups can react with silane hydrogen (Si-H) groups, forming robust crosslinks that enhance the mechanical properties of silicone polymers. This contributes to increased tensile strength, tear resistance, and overall durability of the final silicone product. Whether used in sealants, adhesives, or elastomers, the crosslinking ability of Divinyltetramethyldisiloxane elevates material performance, making it a preferred choice for many industrial applications.
