Product Overview

Polyvinylpyrrolidone (PVP) is a non-ionic polymer available in various viscosity grades that correspond to different molecular weights, classified by K‑value-a characteristic derived from the relative viscosity of its aqueous solution, which directly reflects the average molecular weight (higher K‑values indicate greater viscosity and molecular weight). PVP exhibits excellent solubility in both aqueous and organic solvents, non‑toxicity, and stability to acids, salts, and heat, making it highly versatile across a broad range of industrial applications, including paper production (as a strength enhancer), resin coatings, textile dyeing, inks, imaging, lithography, detergents, ceramics, metallurgy, and as a polymer additive. Its outstanding adhesion, film‑forming, dispersion, and thickening properties also make it a valuable ingredient in the pharmaceutical industry. Specifically, our product-Polyvinylpyrrolidone K25 (PVP K25)-has an average molecular weight of 24,000.

Manufactured by Ulanqab Kema New Material Co., Ltd. in Inner Mongolia, China, using advanced synthesis technology, this high‑performance water‑soluble polymer serves as an effective binder, film former, and dispersant for pharmaceutical, cosmetic, and technical applications (e.g., tablet granulation and pigment dispersion). With stringent quality control that meets international standards and a reliable, direct supply chain from our China‑based production base, our PVP K25 delivers consistent performance and competitive pricing, tailored to the specific needs of B2B customers.

The following table outlines the typical specifications for our Polyvinylpyrrolidone K25.

Polyvinylpyrrolidone K25 is a versatile polymer used across multiple industries. Its unique properties make it a preferred choice for B2B formulators.

1. Pharmaceutical Industry

In the pharmaceutical sector, PVP K25 acts as a crucial binder in wet granulation processes for tablet manufacturing. It improves the compressibility of powders and ensures the tablet's mechanical strength.

• Binder: Effective in low concentrations.
• Film Former: Used in coating solutions.

2. Cosmetics and Personal Care

Due to its film-forming ability and compatibility with various cosmetic ingredients, PVP K25 is widely used in hair styling products (gels, sprays) and skincare formulations.

• Hair Care: Provides hold and shine without stickiness.
• Skin Care: Acts as a moisturizer and stabilizer.

3. Technical and Industrial Applications

Our PVP K25 is also used as a dispersant for pigments and inks, ensuring stability and color intensity.

• Pigment Dispersion: Prevents re-agglomeration of particles.
• Adhesives: Improves initial tack and bonding strength.

Packaging and Storage

We understand that proper packaging is vital for maintaining the quality of Polyvinylpyrrolidone K25 during transit.

• Standard Packaging: 25kg per fiber drum or carton with PE bag inside.
• Custom Packaging: Available upon request for bulk orders.
• Storage: Store in a cool, dry place away from direct sunlight. Keep containers tightly closed when not in use.

1. What is the primary difference between PVP K25 and other K-values?

The "K-value" represents the molecular weight and viscosity of the polymer. Polyvinylpyrrolidone K25 has a medium molecular weight (approx. 25,000–35,000), making it ideal for wet granulation in pharmaceuticals and specific cosmetic formulations where lower viscosity is required compared to K30 or K90.

2. Are you a trading company or a manufacturer?

We are a direct manufacturer. Ulanqab Kema New Material Co., Ltd. operates a production facility in Inner Mongolia, China. This allows us to control the entire production process, ensuring quality and offering competitive factory-direct pricing.

3. What is the solubility of PVP K25?

PVP K25 is highly soluble in water and various organic solvents such as ethanol, methanol, and chloroform. It is hygroscopic, so it should be stored in a dry environment to prevent clumping.

4. Can you provide free samples for testing?

Yes, we understand the importance of testing before bulk purchasing. We can provide free samples (freight collect) so you can verify the quality of our Polyvinylpyrrolidone K25 against your specific requirements.

5. What are your payment terms for international orders?

We typically accept T/T (Telegraphic Transfer) or L/C (Letter of Credit) at sight. For long-term partners, we are open to discussing more flexible payment terms to facilitate smooth trade.
