Polyvinylpyrrolidone  is one of the important excipients advocated internationally. PVP is a white to milky white powder. Easily soluble in water, alcohol, amines and halogenated hydrocarbons, but insoluble in acetone, ether, etc. It has excellent solubility, biocompatibility, physiological inertness, film-forming properties, film protection ability and the ability to combine various organic and inorganic compounds, and is relatively stable to acids, salts and heat.

Some people may have a query: Is PVP a plastic? Here we will make it clear. Although PVP may seems like plastic thing, but actually, Polyvinylpyrrolidone (PVP) is not a plastic, but a polymer compound. PVP, a non-ionic polymer, is one of the most distinctive and widely studied fine chemicals among N-vinylamide polymers. It has a variety of specifications, including industrial grade, pharmaceutical grade and food grade, and is widely used in a variety of fields.

The physical and chemical properties of  Polyvinylpyrrolidone make it unsuitable for classification as plastic. It is a white to light yellow amorphous powder, with deliquability, insoluble in water, alkali, acid and common organic solvents, but has a strong expansion performance and the ability to complex with many kinds of substances. These properties make Polyvinylpyrrolidone an important application in several industries, such as as a disintegrator for tablets in the pharmaceutical industry, or as a stabilizer for extended storage in the beverage industry.

Therefore, while PVP may exhibit plastic-like properties in some applications, such as film formation, it is essentially a polymer compound and does not belong to the plastic category.

Based on the properties of PVP, PVP can be used as a modifier to enhance the mechanical properties and degradation rate of biodegradable plastics. PVP has varies of application in different field.

‌Pharmaceutical field: PVP is mainly used as drug excipients, coating materials and slow and controlled release materials in pharmaceutical industry. Due to its excellent film formation and stability, PVP is often used in the production of drug films, capsules and microspheres, etc., to improve the solubility and bioavailability of drugs ‌.

‌Food processing: PVP  is mainly used as clarifying agent and stabilizer in food processing to improve clarity, stabilize color, improve taste and extend storage period ‌.

‌Daily chemistry: PVP is used in the development of a new generation of hair spray products in daily chemistry, because it has a good affinity with the skin and hair, can form a transparent film, has a protective effect ‌.

‌Paper industry: PVP is used to improve the wet strength of paper, improve gloss, printability and oil resistance ‌.

‌Textile industry: PVP is used in textile industry as softener, antistatic agent and antibacterial agent to improve dyeing power and moisture resistance of fabrics ‌.

‌Lithium battery: PVP is used as a dispersant of lithium battery positive electrode material‌.
