PVP K30 (Polyvinylpyrrolidone) CAS 9003-39-8

Physicochemical Properties

Typical Applications

• Binders in solid formulations: Used in tablet granulation, ceramics, and powder processing where particle binding is required.
• Dispersant and stabilizer: Applied in pigment dispersions, inks, and coatings to improve stability and prevent agglomeration.
• Film-forming agent: Utilized in coatings and specialty formulations where uniform film formation is needed.
• Process aid in detergents and cleaning formulations: Helps maintain dispersion of active components.
• Adhesive systems: Contributes to viscosity control and adhesion performance in water-based systems.

Specific end uses should be evaluated according to formulation requirements and local regulatory considerations.

Packaging

PVP K30 is typically supplied as a hygroscopic powder and packed in moisture-resistant, sealed containers to maintain product stability during storage and transport. Common packaging formats include multi-layer paper bags with inner liners or fiber drums with protective lining.

Packaging is arranged to ensure protection against moisture ingress and contamination, particularly during long-distance export handling. Bulk supply and palletized shipment can be organized based on order volume and logistics requirements.

Storage

Store in a cool, dry, and well-ventilated area. Keep containers tightly sealed to prevent moisture absorption. Avoid exposure to direct sunlight, heat sources, and humid environments.

Maintain package integrity during handling and storage to ensure consistent product performance in downstream applications.

FAQ

• What does “K30” indicate for PVP?
  K30 refers to the viscosity-based classification of the polymer, corresponding to a medium molecular weight range suitable for general-purpose binding and dispersion applications.
• In what form is PVP K30 typically supplied?
  It is generally supplied as a free-flowing powder for easy handling and dissolution in water or compatible solvents.
• Is PVP K30 suitable for water-based formulations?
  Yes, it is highly water-soluble and widely used in aqueous systems as a binder, dispersant, or stabilizer.
• How should PVP K30 be stored to maintain quality?
  It should be stored in sealed containers under dry conditions to prevent moisture uptake, as the material is hygroscopic.
• What documentation is typically available for supply?
  Standard documentation such as COA, TDS, and SDS can be provided to support procurement and formulation evaluation.
• Can packaging be adjusted for bulk orders?
  Yes, packaging formats can be arranged based on order quantity and shipping requirements.
