NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of specialized chemical intermediates, including Bis(dimethylsiloxy)diphenylsilane, identified by CAS No. 17875-55-7. This organosilicon compound, also known as Ph2Si[OSiMe2H]2, is a critical component in the development of advanced silicone materials due to its unique chemical structure and versatile applications. This article delves into the chemistry and industrial significance of this essential trisiloxane.
Bis(dimethylsiloxy)diphenylsilane is characterized by its specific molecular formula, C16H24O2Si3, and a molecular weight of 332.61. Its structure features a central diphenylsiloxy unit flanked by two dimethylsiloxy units, each terminated with a hydrogen atom. This arrangement of silicon-oxygen bonds, along with the presence of phenyl groups, imparts enhanced thermal stability and chemical resistance to the molecules derived from it. The compound typically appears as a colorless to almost colorless clear liquid, with a purity of 97% min, making it suitable for demanding synthesis protocols.
The primary industrial application of Bis(dimethylsiloxy)diphenylsilane is its role as a crosslinking agent in the formulation of silicone elastomers, particularly phenyl silicone rubber and liquid silicone rubber (LSR). In these applications, the Si-H bonds present in the molecule react with vinyl groups or other reactive sites on silicone polymers, forming a three-dimensional network. This crosslinking process is fundamental to achieving the desired mechanical properties, such as tensile strength, elasticity, and thermal stability, required for high-performance applications in sectors like automotive, aerospace, and advanced electronics.
Furthermore, Bis(dimethylsiloxy)diphenylsilane serves as a crucial intermediate in the synthesis of phenyl silicone resins. These resins are valued for their superior thermal stability, radiation resistance, and dielectric properties, which are crucial for encapsulating sensitive electronic components and for protective coatings in harsh environments. The incorporation of the diphenylsiloxy moiety from this trisiloxane enhances the overall performance profile of the resulting resins.
The consistent availability of high-purity Bis(dimethylsiloxy)diphenylsilane from NINGBO INNO PHARMCHEM CO.,LTD. is vital for manufacturers aiming to produce cutting-edge silicone materials. Its role as a key building block facilitates the ongoing innovation in silicone chemistry, enabling the development of materials with tailored properties for an ever-expanding range of technological applications.
In conclusion, Bis(dimethylsiloxy)diphenylsilane (CAS 17875-55-7) is a compound of significant industrial importance, underpinning advancements in silicone technology. Its chemical structure and reactive capabilities make it an indispensable intermediate and crosslinker for high-performance phenyl silicone materials. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying this essential chemical to support global innovation in the field.
