In the vast field of materials science, there is a special class of compounds that are quietly changing our lives, and that is hydrogen-terminated phenyl polysiloxane IOTA 233. Maybe this name sounds a little strange and difficult to pronounce, but it plays an indispensable role in many fields.

Hydrogen-terminated phenyl polysiloxane, from a chemical structure point of view, is a hydrogen-terminated T-type phenyl polysiloxane. Its molecular weight ranges from 550 to 3000. Don't underestimate this range. It is this molecular weight that gives it unique properties. It has a series of names. The Chinese name is hydrogen-terminated polyphenyl-(dimethylsiloxy) siloxane, the Chinese alias is hydrogen-terminated phenyl polysiloxane, and the English name is Polyphenyl-(dimethylsiloxy) siloxane hydride terminated. There are also many English aliases. Its CAS number is 68952-30-7, which is like its unique "ID number" in the chemical world.

In terms of appearance, hydrogen-terminated phenyl polysiloxane IOTA 233 is a colorless, transparent, viscous liquid that looks ordinary, but its performance is excellent. Its specific gravity is between 1.00 and 1.01, its refractive index is 1.46 to 1.52 at 20°C, its viscosity is 5 to 5000 mm²/s at 25°C, its flash point (COC) is greater than 110°C, and its content (H%) is between 0.35 and 0.75. These seemingly simple data actually determine its performance in various applications.

One of its most prominent characteristics is its good compatibility with a variety of materials, such as methyl silicone oil, liquid silicone rubber, phenyl silicone rubber, phenyl silicone resin, etc. This good compatibility makes it an ideal choice in material modification and synthesis. For example, it can be used as a crosslinking agent for addition silicone rubber, phenyl silicone rubber, and phenyl silicone resin. In the production process of silicone rubber, adding hydrogen-terminated phenyl polysiloxane IOTA 233 can form a tighter connection between the molecular chains of silicone rubber through cross-linking reaction, thereby improving the strength, heat resistance and chemical stability of silicone rubber.

In practical applications, hydrogen-terminated phenyl polysiloxane IOTA 233 is used in many fields. In the electronics field, it can be used to manufacture packaging materials for electronic components with its good insulation and heat resistance, protect electronic components from the influence of the external environment, and ensure the stable operation of electronic equipment. In the aerospace field, since aerospace vehicles need to withstand extreme temperatures and complex environments, the use of high-performance materials with hydrogen-terminated phenyl polysiloxane can meet the strict requirements of aerospace vehicles for material performance. In automobile manufacturing, it can also be used to manufacture sealing materials and high-temperature resistant parts of automobile engines to improve the performance and reliability of automobiles.

In terms of storage and packaging, hydrogen-terminated phenyl polysiloxane IOTA 233 is usually packaged in 15kg and 200kg coated iron barrels and needs to be stored in a ventilated and cool place. This is because it can maintain the stability of its performance under specific environmental conditions.
Although hydrogen-terminated phenyl polysiloxane IOTA 233 is not common in our daily life, it plays an important role in many fields with its unique properties and wide application. With the continuous development of materials science, its application prospects will be broader.
