Professional PVP, VP/VA Copolymers, PVPP, PVP-Iodine Suppliers in China

PVP has excellent physiological inertia, does not participate in human metabolism, and has excellent biocompatibility, and does not cause any irritation to the skin, mucous membranes, eyes, etc. Pharmaceutical grade PVP is one of the three new pharmaceutical excipients advocated internationally, which can be used as binder for tablets, granules, co-solvent for injections and flow aid for capsules. Ophthalmic detoxification agent, delay agent, lubricant and coating film agent, liquid preparation of dispersing agent and enzyme and heat-sensitive drug stabilizer, also can be used as cryoppreservation agent. For contact lenses, can increase its hydrophilicity and lubricity.

PVP itself is not carcinogenic, has good food safety, and can form complexes with specific polyphenol compounds (such as tannins). In food processing, PVP is mainly used as food clarifier and stabilizer for beer, juice, wine and other food. PVP can form complexes with specific polyphenol compounds (such as tannins), which can play a clarifying and anticoagulant role in fruit juice drinks. PVP can also be used in the production of wine, vinegar, etc. Cross-linked PVP is especially widely used in beer and tea drinks. Polyphenols in beer can combine with proteins in beer to generate tannic macromolecular complex, which will seriously affect the flavor of beer and shorten its shelf life. The cross-linked polyvinylpyrrolidone (PVPP) can be complex with tannins and anthocyanins in beer, so as to clarify beer, and improve the stability of beer storage, prolong the shelf life. In tea beverage, the use of PVPP can properly reduce the content of tea polyphenols, and PVPP does not remain in tea beverage, can be reused, greatly reducing the cost.

In the consumption structure of PVP, cosmetics industry in developed countries accounts for 30% ~ 50%, and China accounts for 70% ~ 80%. Because PVP has very low toxicity and physiological inertia, it has no irritation to the skin and eyes, and has a long-term use record in the field of medicine, so it is very safe to be used in cosmetics. In daily cosmetics, PVP and copolymer have good dispersion and film formation, PVP has the role of protecting colloid in emulsion, can be used in fatty and non-fatty paste, as setting liquid, hair spray and mousse setting agent, hair care agent shading agent, shampoo foam stabilizer, wave setting agent and hair dye dispersant and mixture. Add PVP to cream, sunscreen and hair remover to enhance wetting and lubrication.

PVP has a good affinity with many organic dyes. It can be combined with hydrophobic synthetic fibers such as polyacrylonitrile, ester, nylon and fibrous materials to improve dyeing power and hydrophilicity.

PVP coated paint, coating film transparent without affecting the color, improve the gloss and dispersion of paint and pigment, improve thermal stability and improve the dispersion of ink and ink, etc.

Polyvinylpyrrolidone, as a polymer surfactant, can be used as dispersant, emulsifier, thickener, leveling agent, particle size regulator, anti-reprecipitating agent, coagulant, co-solvent and detergent in different dispersion systems.

PVP can be used as a gelling agent for tertiary oil recovery to improve oil recovery rate. As an additive to the photosensitive material, it helps to reduce the degree of emulsion and enhance the overlay ability of the developed image. In the process of polymer polymerization as a thickening agent, dispersion stabilizer and bond regulator. In paper industry as a dispersant, in acrylamide gasification reaction as a catalyst. PVP is also being used in separation films, photocuring resins, laser optic discs, drag reduction coatings, building materials, steel making and electroplating.
