Thermo Scientific™ PVP K12 is a low molecular weight polyvinylpyrrolidone polymer with a K-value of 10–14, supplied as a white to yellowish-white powder or flakes. It is used extensively as a binder, film-former, dispersant, stabilizer, and viscosity modifier in research, pharmaceuticals, and analytical chemistry. With high purity, low residual monomer content, and excellent solubility in water, this PVP variant is ideal for applications requiring low-viscosity polymer solutions.
Key Features
- Low molecular weight (∼3500) for high solubility and low viscosity applications
- Highly pure with minimal residual monomer (≤10 ppm)
- Broad functional utility as dispersant, complexing agent, and stabilizer
- Low water content (≤5%) and heavy metals (≤10 ppm) for reproducibility in sensitive applications
- Supplied as free-flowing powder or flakes
