Overview of Hydroxyl Terminated Polydimethylsiloxane Silanol Terminated Pdms/Polymer Oh
Polymer surfactants, also known as polymeric surfactants or amphiphilic polymers, are high-molecular-weight compounds that combine the properties of traditional low-molecular-weight surfactants with the unique features of polymers. Unlike small molecule surfactants, polymer surfactants offer enhanced stability, improved solubility, and the ability to form more complex structures such as micelles, hydrogels, and vesicles. These macromolecules find applications across a wide range of industries due to their tailored structures and tunable properties, which allow for precise control over interfacial behavior and solution rheology.

Specification of Hydroxyl Terminated Polydimethylsiloxane Silanol Terminated Pdms/Polymer Oh
Hydroxyl Terminated Polydimethylsiloxane (Silanol Terminated PDMS/Polymer OH) is a silicone-based polymer with unique properties. It is widely used in industries like coatings, adhesives, electronics, and medical devices. The product has a flexible backbone structure made of repeating dimethylsiloxane units. Its hydroxyl (-OH) end groups enable reactivity, making it ideal for cross-linking or modifying other materials.
The molecular weight typically ranges between 500 and 100,000 g/mol. This range allows customization for different applications. The viscosity varies from 10 to 1,000,000 centipoise (cP). Lower viscosity grades flow easily for coatings. Higher viscosity grades provide thickening effects in gels or rubbers. The hydroxyl content is between 0.1% and 10% by weight. Higher hydroxyl levels boost reactivity for chemical bonding.
The material appears as a clear, colorless liquid or semi-solid. It remains stable at temperatures from -50°C to 200°C. This thermal stability suits high-heat environments. It resists oxidation, UV radiation, and moisture. These traits ensure long-term durability. The density is around 0.97 to 1.00 g/cm³. It dissolves in common solvents like toluene, xylene, or hexane. This aids formulation processes.
The polymer is chemically inert. It does not react with most substances. This prevents contamination in sensitive applications. It has low surface tension. This allows it to spread evenly on substrates. The material is non-toxic. It meets safety standards for medical and food-grade uses.
Applications include sealants for electronics, where flexibility and insulation matter. It acts as a release agent in molding processes. It modifies rubbers to enhance elasticity. In cosmetics, it adds smoothness to creams. For adhesives, it improves bonding strength. The polymer works as a defoamer in industrial fluids.
Storage requires keeping it sealed in a dry, cool place. Exposure to moisture causes premature curing. Shelf life is up to 12 months under proper conditions. Compatibility testing is recommended before mixing with other chemicals. This ensures optimal performance.
