NINGBO INNO PHARMCHEM CO.,LTD. aims to be your most trusted partner in chemical sourcing. This guide focuses on Silanol Terminated Polydimethylsiloxane (CAS 70131-67-8), a crucial material for a multitude of industrial applications. Understanding its properties and applications is key for making informed purchasing decisions. We are a premier manufacturer of Silanol Terminated Polydimethylsiloxane, committed to providing clear information to our clients.

The primary identifier for this chemical is its CAS Number: 70131-67-8. This universally recognized number ensures you are procuring the correct substance. Silanol Terminated Polydimethylsiloxane is characterized by its molecular structure, which includes reactive silanol (-OH) groups at each end of the polydimethylsiloxane chain. This structure dictates its behavior, particularly its ability to cure at room temperature when exposed to moisture or specific catalysts, forming cross-linked networks. This is the basis for its use in RTV (Room Temperature Vulcanizing) silicone formulations, widely employed as sealants, adhesives, and encapsulants.

Key properties that make this polymer highly desirable include its liquid state (colorless transparent flow liquid), excellent thermal stability (maintaining elasticity between -60°C and 200°C), superior electrical insulation, and robust resistance to water, odor, and weathering. These characteristics are essential for its performance in demanding applications such as construction caulking silicone, where durability against environmental factors is critical, and in electronic insulation silicone, where reliable dielectric properties are non-negotiable.

When considering where to buy Silanol Terminated Polydimethylsiloxane, industrial buyers should look for suppliers who can guarantee consistent quality, reliable supply, and technical support. Factors such as viscosity, purity, and the concentration of silanol groups can vary and are critical specifications depending on the intended application. For instance, different viscosities are preferred for different uses, from fabric finishing to more viscous sealant applications. Understanding your specific needs will help you choose the right grade from your supplier of Silanol Terminated Polydimethylsiloxane.

Beyond its primary applications, its role as a fabric finishing silicone fluid and a personal care silicone raw material highlights its adaptability. In textiles, it provides a soft feel and improved performance, while in personal care, it enhances texture and efficacy. These diverse uses underscore the importance of understanding the full scope of OH-terminated PDMS applications. Purchasing this material at a competitive Silanol Terminated Polydimethylsiloxane price, while maintaining quality, is a strategic goal for many businesses.
