Appearance: White to slightly yellow powder or transparent, translucent granules, odorless or slightly odorous.

Solubility: Soluble in water, ethanol and other polar solvents; practically insoluble in chloroform, acetone, ether

Hygroscopicity: It has strong hygroscopicity, which changes with the degree of polymerization and ambient humidity. When the relative humidity is high, the hygroscopicity is more obvious.

Thermal stability: It has good thermal stability. Within a certain temperature range, solid PVP can remain stable. Stable at room temperature; may discolor or crosslink at elevated temperatures.

Film-forming property: After the solution is coated, the water evaporates to form a transparent, flexible, continuous film with excellent film-forming properties.

Application Areas

In the pharmaceutical field: used as a binder, coating material, solubilizer and thickener; used as a cosolvent and thickener in liquid preparations to improve solubility and dispersibility; used as a drug carrier to help slow and controlled release; used to make medical polymer materials with good biocompatibility.
In the food field: used as a food additive to clarify beer and other beverages; used in food packaging materials to enhance performance and extend shelf life.
In the cosmetic field: used as a thickener and film-forming agent in skin care products to moisturize and protect against the sun; used as a setting agent and thickener in hair products to solidify and enhance gloss and elasticity.

What are the advantages of the production process of PVP products? 

The internationally leading suspension polymerization and solution polymerization processes are adopted. The production process is precisely controlled in temperature and speed to ensure uniform molecular weight distribution, high batch stability of products, and impurity generation rate is lower than the industry average.

How to ensure that Polyvinylpyrrolidone (PVP) meets environmental protection requirements?

The entire production process follows green chemical standards, wastewater and waste gas are discharged in accordance with standards after multi-stage treatment, and both raw materials and finished products have passed environmental certification such as REACH, which meets the needs of sustainable development.

Are samples provided? Are samples charged? 

50-200g standard samples can be provided free of charge, and customized samples require a small cost fee. The samples are delivered in professional sealed packaging or professional packaging throughout the process to ensure that the quality is not damaged.

Does Polyvinylpyrrolidone (PVP) have complete export qualifications? 

It has complete export qualifications, including FDA, GMP, COS and other certification documents, and can provide materials required for customs clearance such as certificates of origin and health certificates to help global trade.
