The Povidone (PVP) K series encompasses a range of water-soluble polymers, each distinguished by its 'K' value, which correlates to its average molecular weight and solution viscosity. This differentiation is crucial for formulators as it dictates the specific applications and performance characteristics of each grade. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing these diverse grades, including Povidone K17, K30, and K90, understanding that selecting the right K value is key to product success in pharmaceuticals, cosmetics, and industrial sectors.

Povidone K17, with its lower molecular weight, is favored for applications requiring excellent solubility and lower viscosity. In pharmaceuticals, it often serves as a solubilizer and stabilizer in injectable formulations and as a cosolvent. Its role as a povidone k17 pharmaceutical excipient highlights its suitability for precise formulations. In cosmetics, it's used in styling aids and skincare products where a lighter touch is desired.

Povidone K30 represents a versatile mid-range option, offering a balanced blend of binding strength and solubility. It is a workhorse in tablet manufacturing, acting as an excellent binder for both wet and dry granulation processes. Its intermediate viscosity makes it adaptable for a wide array of pharmaceutical dosage forms, including oral solids and some liquid preparations. The widespread application of PVP K30 binder is a testament to its balanced properties.

Povidone K90, at the higher end of the molecular weight spectrum among these common grades, boasts the strongest binding and film-forming capabilities. Its higher viscosity makes it ideal for applications demanding robust adhesion and film integrity, such as in demanding tablet binding applications, creating durable films for coatings, or as a viscosity enhancer in industrial products. The powerful adhesive properties of PVP K90 binder are often sought after for challenging formulations.

Understanding these distinctions allows manufacturers to select the optimal Povidone K grade for their specific needs. Whether you require the solubilizing power of K17, the balanced binding of K30, or the strong adhesion of K90, choosing the right partner is essential. NINGBO INNO PHARMCHEM CO.,LTD. is a leading manufacturer in China dedicated to providing high-quality Povidone K series polymers. We offer competitive povidone k17 price and other grades, ensuring you can buy povidone k that meets your exact specifications for pharmaceutical, cosmetic, or industrial applications.
