Structural characteristics
Linear molecular structure, composed of pyrrolidone rings and vinyl rings connected alternately, presenting a hydrophilic chain structure.
Molecular weight is distinguished by model (such as K30 average molecular weight of about 58,000, K90 about 1,300,000)

Solubility
Soluble in water, ethanol, amines and halogenated hydrocarbons to form colloidal solutions; insoluble in organic solvents such as acetone and ether.
The pH value of aqueous solution is usually 3.0-7.0 (low molecular weight model) or 5.0-9.0 (high molecular weight model).

Physical properties
Appearance is white to light yellow powder, storage conditions are room temperature dry environment, the shelf life is usually ≥3 years.

Application

Cosmetics: used for hair gel styling, hair dye dispersion and thickening, skin care products moisturizing film formation;
Food: used to prevent turbidity and precipitation in beverages, improve dough in baking, used in food packaging;
Others: used as dispersing and thickening agent for coatings and inks, removing impurities and preventing scale in water treatment, and used in fabric processing in textile printing and dyeing.

Q: How is the quality of poly vinylpyrrolidone pvp products guaranteed?
A: We use automated polymerization equipment imported from Germany to strictly control the purity of NVP monomers ≥ 99.9%, and have passed ISO 9001 and GMP dual certification. Each batch is tested for 12 indicators such as molecular weight distribution and residual monomer content (<0.05%), and a third-party test report is provided.

Q: Can products of different specifications be customized?
A: We support customized K value (K12-K120), molecular weight (10,000-1.5 million) and dosage form (powder, granules, solution). We can adjust the polymerization process according to customer needs, and produce samples in as fast as 3 days, and complete small-scale optimization in 7 days.

Q: What is the price advantage of poly vinylpyrrolidone pvp?
A: We have our own NVP raw material production line, and large-scale production reduces costs. Annual purchases of more than 50 tons enjoy tiered discounts, and we support joint research and development of cost-effective products. For example, replacing some imported raw materials with low K value PVP can reduce costs by 20%.
