N-vinyl pyrrolidone (NVP) has a variety of uses, mainly including the following aspects:
Industrial applications:
Adhesives and coatings: NVP can be added to the formulation of UV-curing coatings to form a flexible and hard plastic film, improving the physical properties of the product. In the wood flooring industry, the addition of NVP to UV-resistant coatings can provide physical properties equivalent to wax-free floors
Paper or paperboard: NVP is used in UV and EB-curing coatings, requiring low viscosity and high reactivity, and these standards are met by improving fluidity and measurement levels, and maintaining good curing characteristics
Textile industry: NVP is used as a dyeing auxiliary, etc.
Other industrial applications: NVP is also used to produce homopolymers and copolymers that require good modeling, such as polyvinyl pyrrolidone (PVP) series products. It is also used as a dispersant and paint additive in the paper industry.
Medical applications:
Radiation medicine: Adding NVP to radiation medicine formulas can improve the elongation rate, viscosity and other properties of high-gloss and low-gloss coatings, thereby meeting the high requirements of material properties in the medical field.
Pharmaceutical field:
Pharmaceutical intermediates: NVP, as a pharmaceutical intermediate, has important applications in the pharmaceutical industry.
Other applications:
Cosmetics: NVP homopolymers and copolymers have low toxicity and water solubility and can be used in the preparation of cosmetics.
Plastics: NVP can be used in the formulation of UV-curing coatings to form flexible and hard plastic films.
