At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the critical role that specialized chemical intermediates play in advancing material science. Tetramethyldivinyldisiloxane (CAS 2627-95-4) is one such compound, offering distinct technical advantages for manufacturers working with silicone technologies. This article aims to illuminate its key properties and applications, especially for those seeking to optimize their silicone formulations.

Tetramethyldivinyldisiloxane, also known as Divinyltetramethyldisiloxane, is characterized by its high purity, typically 99% minimum, and its liquid form, appearing as a colorless to yellowish transparent liquid. Its chemical formula is C8H18OSi2, with a molecular weight of 186.40. These basic properties are foundational to its performance, but its true value lies in its functional application.

Primarily, Tetramethyldivinyldisiloxane serves as a linear inhibitor in two-part Silicone RTV-2 Addition Curing systems. This function is critical for controlling the rate of the platinum-catalyzed curing process. The compound's high vinyl content makes it particularly effective at retarding the reaction, thus extending the pot life and working time of the silicone mixture. This extended working time is essential for processes that require intricate application or where larger batches are being prepared, allowing for better handling and reduced waste. Understanding the price point and buy options for this chemical is crucial for cost-effective manufacturing.

Beyond its role as an inhibitor, Tetramethyldivinyldisiloxane is also utilized as an end-capper in the production of vinyl end-capped siloxane polymers. These polymers are vital building blocks for a variety of silicone products, including elastomers, sealants, and coatings. The precise placement of vinyl groups at the polymer chain ends dictates the reactivity and ultimate properties of the finished silicone material. Therefore, the quality and consistency of Tetramethyldivinyldisiloxane are paramount for achieving desired outcomes.

The technical advantage of its relatively low boiling point (139°C) is another noteworthy aspect. This property ensures that the inhibitor readily volatilizes during the curing cycle, leaving no residual traces that could compromise the performance of the cured silicone. Standard formulations often recommend using between 0.25% and 0.50% by weight of Tetramethyldivinyldisiloxane relative to the base polymer containing the platinum catalyst, a testament to its potency and efficiency.

For manufacturers and researchers looking for reliable sources to purchase Tetramethyldivinyldisiloxane, NINGBO INNO PHARMCHEM CO.,LTD. offers high-quality grades backed by robust technical support and efficient logistics. This commitment ensures that clients can consistently obtain this vital intermediate for their innovative silicone applications.
