NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing high-quality chemical solutions, and among our flagship products are the polyethylsiloxane fluids. These compounds, also known by their CAS number 63148-61-8, are distinguished by a set of unique properties that make them invaluable across numerous applications. Understanding these characteristics is key to leveraging their full potential in your specific industry.

Chemically, polyethylsiloxane fluids are noted for their inertness. They are colorless, odorless, and resistant to degradation, ensuring they do not adversely affect the materials they come into contact with. This chemical stability is crucial for applications where purity and non-reactivity are paramount, such as in certain manufacturing processes or specialized industrial formulations. Their inert nature also contributes to their long shelf life and reliability.

A key technical characteristic is their compatibility with a wide array of substances. Polyethylsiloxane fluids exhibit full compatibility with mineral and synthetic oils, which is a significant advantage in lubrication and hydraulic systems. This ensures seamless integration and prevents phase separation or degradation of the mixture. Furthermore, they demonstrate inertness towards structural and functional materials, including various metals, alloys, plastics, polymers, and rubbers. This broad compatibility simplifies their use and minimizes risks of material incompatibility.

The thermal properties of these fluids are also noteworthy. They possess excellent lubricating properties and a low gel point, typically below -70°C. This makes them suitable for applications operating in extremely cold environments, ensuring that mechanisms and instruments continue to function reliably. They are also utilized as heat transfer agents, capable of operating efficiently at temperatures ranging from 150°C to 250°C in both open and closed systems. This wide operational temperature window highlights their robustness and adaptability.

In terms of physical properties, these fluids are typically liquids, ranging in color from colorless to pale yellow. Their viscosity varies, with common specifications including ranges like 34-40 mm²/s and 180-280 mm²/s at 25°C. The flash point is typically above 170°C, indicating good safety characteristics regarding flammability. Their density at 20°C is around 0.95-1.02 g/cm³, which is comparable to many organic oils.

The combination of these properties—chemical inertness, broad compatibility, excellent lubrication, and thermal stability—makes polyethylsiloxane fluids exceptionally versatile. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying these advanced materials, enabling industries to achieve higher performance, greater efficiency, and improved product quality through tailored chemical solutions.
