Détails

Polyvinylpyrrolidone K30 (K29-32), designated as Model MA-EN-BI-0012 by Canrd, is a nonionic polymer with an average molecular weight of approximately 58,000. This product is developed for applications requiring excellent solubility in water, alcohols, amines, and halogenated hydrocarbons, along with stability toward acids, salts, and heat. Its film-forming ability, biocompatibility, and capacity to form complexes with organic and inorganic compounds make it suitable for use as a dispersant and binder in experimental and energy materials. Common use scenarios include absorbing phenols and tannic acids from aqueous extracts for plant enzyme purification, as well as serving as a chromatographic adsorbent for separating aromatic acids, aldehydes, and phenols. Available in 20 g, 100 g, and 500 g quantities, this PVP grade offers reliable performance for research and development tasks in materials science and biochemistry.

PVP has excellent solubility, biocompatibility, physiological inertness, film-forming ability, membrane protection ability, and ability to form complexes with various organic and inorganic compounds. It is stable to acids, salts, and heat, and therefore has a wide range of applications.

Used to absorb phenols and tannic acids from aqueous extracts for the purification of plant enzymes. Used as a chromatographic adsorbent for the separation of aromatic acids, aldehydes, and phenols.

Average molecular weight: 58000.

PVP is soluble in water, alcohols, amines, and halogenated hydrocarbons, but insoluble in acetone, ether, etc.
