Industrial Grade PVP K30 - Water-Soluble Polymer for Coatings, Adhesives and Textiles

Industrial Grade PVP K30 - Water-Soluble Polymer for Coatings, Adhesives and Textiles Dispersing Agent for Inks

INCI:Polyvinylpyrrolidone

CAS No.: 9003-39-8

Description :

In the industrial and special application fields, polyvinylpyrrolidone K30, due to its outstanding dispersibility, film-forming ability, adhesion and chemical stability, has become a key additive in several high-tech industries. Its core value lies in solving the process problems such as dispersion, stability and adhesion in production.

Application in the industrial field:

1. Coatings, inks and pigments: Prevent pigments from settling and caking, enhance the stability of the system, glossiness and color uniformity.
2. Adhesive: As a component of pressure-sensitive or rewettable adhesives, it has excellent adhesion to various substrates such as plastics, glass, and metals.
3. Textile printing and dyeing: Enhance the dispersibility of dyes, improve the uniformity and color fastness of dyeing; prevent the re-deposition of dirt in detergents
4. Membrane separation technology: Used to manufacture separation membranes for blood dialysis, water treatment, etc., it helps to form uniform micropores and significantly enhances the hydrophilicity and water flux of the membranes.
5. Electronics and New Energy: Battery Paste: Dispersion of electrode active materials (such as carbon materials, metal oxides), to improve uniformity and battery performance; Semiconductors: Used in photoresist, grinding fluid, cleaning solution, taking advantage of their dispersibility and easy water-washability.
6. Ceramic processing: As a temporary adhesive in the ceramic mold, it enhances the strength of the green body; at the same time, it uniformly disperses inorganic powders.
7. Other special applications: as a polymer surfactant, a particle size regulator for polymer reactions, and a photographic film additive, etc.

Characteristics:

1. Outstanding solubility and compatibility: It can dissolve in water as well as in various organic solvents such as alcohols and chloroform, enabling its flexible application in different systems.
2. Excellent dispersion and stability capabilities: The long polymer chains can adsorb onto the particle surface, forming spatial steric hindrance, effectively preventing agglomeration. This is particularly effective for stabilizing carbon nanotubes (CNT), pigments, and other nano or micrometer-sized particles.
3. Strong adhesion and film-forming property: After the solution dries, it can form a transparent and tough film, and has good adhesion to various materials. This is the foundation for it to be used as an adhesive and film-forming agent.
4. High chemical stability and inertness: Good heat resistance (the glass transition temperature Tg is approximately 160-170°C), stable solution viscosity under different pH and salt concentrations, and high physiological inertness
