Hydroxy Silicone Oil, scientifically known as Hydroxy Terminated Polydimethylsiloxane Silicone Oil (CAS 70131-67-8), is a highly versatile silicone fluid that serves as a cornerstone in numerous industrial applications. This OH Polymer is a colorless, transparent liquid characterized by the presence of reactive hydroxyl groups at both ends of its polydimethylsiloxane chain. These hydroxyl groups are key to its ability to undergo reactions such as cross-linking and esterification, making it invaluable for formulators.

The intrinsic properties of this silicone fluid are quite remarkable. It boasts excellent thermal stability, capable of withstanding temperatures from -50°C to 250°C, alongside superior electrical insulation capabilities. Its chemical inertness, low surface tension, and good water repellency further enhance its utility across a broad spectrum of uses. For manufacturers, sourcing this material from a reliable China supplier ensures consistent quality and competitive pricing, often benefiting from efficient production processes.

The applications of Hydroxy Silicone Oil are extensive. In the electronics industry, it functions as an insulating and encapsulating material, protecting sensitive components. The construction sector utilizes it in sealants and coatings due to its weather resistance and adhesion. The textile and leather industries benefit from its use as a softening and finishing agent, improving fabric feel and sewability. It is also a crucial component in the production of silicone rubber, adhesives, and release agents.

When considering a purchase, understanding the specifications, particularly the viscosity and hydroxyl content, is crucial. These parameters dictate the fluid's reactivity and performance in specific formulations. Buyers looking for this OH Polymer can trust that manufacturers in China provide detailed technical data sheets to aid in selection. Whether you are developing advanced adhesives, high-performance textiles, or robust electronic components, this Hydroxy Silicone Oil, supplied by dedicated manufacturers, offers a reliable and cost-effective solution.
