Poly 1 Vinylpyrrolidone Co Vinyl Acetate

Appearance: It usually appears as white to light yellow powder or granules, with uniform texture and no obvious impurities. This form is conducive to dispersion and application in different systems. ​

Solubility: It exhibits good solubility in water and various organic solvents such as ethanol and acetone. It can form a uniform and stable solution with water, and can also quickly disperse and dissolve in organic solvents. This feature greatly expands its application range in different formulation systems, and it can be well adapted to both water-based products and oily products. ​

Film-forming property: When the solution containing the copolymer evaporates the solvent, it can form a continuous, transparent and flexible film on the surface of the object. The film has good adhesion and can firmly adhere to the surface of various materials. This feature makes it have important applications in coatings, cosmetics and other fields. ​

Stability: Under normal storage conditions, the chemical properties are stable and it is not easy to decompose, oxidize and react. It has good weather resistance and can maintain stable performance for a long time in different temperature and humidity environments, which provides a guarantee for the long-term storage and use of the product.

Application Areas

Cosmetics: hairspray, mousse, styling and moisture resistance; thickening and conditioning in shampoo, improving hair combing performance.
Medicine: tablet binder and coating material, improving drug stability and bioavailability; improving the spreadability of topical preparations.
Other industries: dispersing pigments in coatings; enhancing material adhesion in adhesives.

Q: How to ensure the quality stability of poly 1 vinylpyrrolidone co vinyl acetate products?
A: We use an automated free radical polymerization production line to monitor temperature, pressure and other parameters in real time throughout the process, strictly control the monomer ratio and initiator dosage, and each batch of products passes more than 10 quality inspections such as infrared spectroscopy and molecular weight detection to ensure that the key indicators such as film-forming property and solubility meet the standards by ≥99.5%.

Q: Can poly 1 vinylpyrrolidone co vinyl acetate provide products of different specifications?
A: We support customized products with different molecular weights (50,000 - 500,000) and monomer ratios (VP/VA 6:4 - 8:2). We can also provide powder, granule or solution dosage forms according to customer needs, and produce samples in as fast as 7 working days.

Q: What are the advantages of your products compared with competing products?
A: Through special processes, the residual monomer content is reduced to less than 0.1%, which is safer in pharmaceutical-grade applications; the film-forming speed is 20% faster than similar products, and the compatibility of cosmetic formulas is improved by 30%, which can significantly optimize customer production efficiency.
