In the intricate science of silicone formulation, understanding the role of viscosity is fundamental. Hydroxyl Terminated Polydimethylsiloxane (HO-PDMS), a key silicone fluid, is available in a spectrum of viscosities, each offering unique benefits for various applications. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier of these specialized fluids, guides formulators in selecting the optimal HO-PDMS grade for their needs.

The viscosity of HO-PDMS, often measured in centistokes (cSt) at 25°C, directly influences its processing characteristics and the final properties it imparts to a formulation. For instance, lower viscosity fluids (e.g., 25-100 cSt) are often favored as reactive diluents to reduce the overall viscosity of silicone rubber or sealant systems, improving workability and application ease. These grades are also excellent for surface treatments where thin, uniform films are required.

Conversely, higher viscosity HO-PDMS fluids (e.g., 1,000 cSt to 200,000 cSt and above) are typically used as the primary polymer matrix in adhesives, pressure-sensitive adhesives (PSAs), and certain types of silicone elastomers. Their inherent body and cohesive strength contribute to the structural integrity and performance of the end product. As a dedicated manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. provides a comprehensive range of viscosities to meet diverse industrial demands. We encourage product developers and procurement managers to buy with confidence from a trusted supplier.
