●Adjustable performance: different copolymer monomers can be introduced to optimize solubility, film-forming properties, etc., such as copolymerization with acrylates to enhance film hardness and water resistance, and hydrophilic monomers to improve water-soluble dispersibility.
●Strong compatibility: It has good adaptability with various substances such as surfactants and solvents, and is not easy to precipitate and stratify in complex formulas, ensuring system stability.
●Good biocompatibility: It continues the non-toxic and non-irritating characteristics of polyvinyl pyrrolidone, and is safely used in the fields of medicine and cosmetics, and can contact human tissues.
●Adsorption and complexation ability: Some copolymers can adsorb and complex specific substances, which are used for separation, purification and stabilization of active ingredients.
Drug carrier: used to prepare nanoparticles (such as paclitaxel nanoparticles) to enhance drug solubility and targeting.
Disinfection and wound healing: combined with iodine to form povidone iodine (PVP-I), which has a broad spectrum of bactericidal effects and low irritation.
Cosmetics
Thickening and moisturizing: used to adjust viscosity in lotions and essences to improve skin feel; but be aware that it may cause allergic reactions.
Water treatment: modified nano zero-valent iron (NZVI) is used to remove pollutants in water (such as tetracycline).
Adhesives and coatings: PVP/VA copolymers are used for antistatic coatings on paper and textiles.
FAQ
Q: What are the advantages of polyvinylpyrrolidone copolymer over homopolymer?
A: Copolymers have more flexible performance. By adjusting the type and ratio of monomers, the solubilization, film-forming or adsorption can be enhanced to meet the needs of multiple scenarios.
Q: What are the product specifications and minimum order quantity?
A: We provide different monomer ratios and molecular weight specifications. The minimum order quantity for conventional products is 1 ton, and the minimum order quantity for customized products is 3 tons. The delivery cycle is 10-15 days.
Q: Does the product meet safety standards?
A: It has passed FDA and EU REACH certification, meets the safety requirements of the pharmaceutical, food, cosmetics and other industries, and can provide test reports.
Q: Will it affect stability in complex formulas?
A: It has strong compatibility and good compatibility with various surfactants and solvents. It has been tested that there is no precipitation or stratification in the multi-component system.
Q: Can special performance products be customized?
A: Customization is supported. The copolymer monomers and polymerization processes can be adjusted according to customer needs to develop exclusive solubilization, sustained release and other functional products.
