Functional polymer "Polyvinylpyrrolidone and copolymer products"
We handle "polyvinyl pyrrolidone and copolymer products (vinyl acetate-styrene)" used for thickening, dispersing, adhesion, binding, and emulsification stability, among other applications.
The acetylene derivatives handled by our company are a product group based on acetylene as the starting raw material. We handle products used in a wide range of fields such as solvents, surfactants, monomers, and functional polymers. Our company has been engaged in sales activities in Japan for many years and supports our customers' product development with extensive product knowledge. We handle functional polymers of acetylene derivatives, specifically "Polyvinylpyrrolidone and copolymer products"! 【Representative Products】 ■ Polyvinylpyrrolidone ■ Polyvinylpolypyrrolidone ■ Alkylated Polyvinylpyrrolidone ■ Vinylpyrrolidone/Vinyl Acetate Copolymer ■ Vinylpyrrolidone/Styrene Copolymer 【Basic Properties】 ■ Thickening ■ Adhesion ■ Dispersion ■ Emulsification stability ■ Aggregation *For more details, please refer to the PDF document or feel free to contact us.
basic information
【Representative Characteristics】 <Povidone> A hygroscopic, amorphous polymer that can be provided as a highly fluid powder or aqueous solution. It is available in various grades from low molecular weight to high molecular weight. It is soluble in water and organic solvents, non-toxic, and a safe functional polymer. <PVP> A highly cross-linked, fluid polymer derived from povidone. It is insoluble in water and organic solvents but retains many of the functional properties of povidone. <Alkylated Povidone> A highly cross-linked, fluid polymer derived from povidone. It is insoluble in water and organic solvents but retains many of the functional properties of povidone. <Vinylpyrrolidone/Vinyl Acetate Copolymer> A linear random copolymer with a vinylpyrrolidone/vinyl acetate ratio of 70/30 to 30/70. As the vinylpyrrolidone content increases, the hydrophilicity also increases. <Vinylpyrrolidone/Styrene Copolymer> A graft copolymer with a polyvinylpyrrolidone/styrene ratio of 30/70. *For more details, please refer to the PDF document or feel free to contact us.

Applications/Examples of results
【Representative Uses】 <PVP (Polyvinylpyrrolidone)> Dispersing stabilizer for dyes/raw materials in inks and writing inks. Acceptable layer for inkjet printing. Used for void formation during hollow fiber membrane production, as a binder for adhesive applications, and for other dispersion stabilization and thickening purposes. <Polyvinylpyrrolidone> Hygroscopic and forms strong complexes with electron-donating substances such as tannins, flavonoids, and dyes, adsorbing various substances including colors from dyes, printing inks, and polyphenols. <Alkylated Polyvinylpyrrolidone> Can also be used as a pigment dispersant in organic solvent-based inks and coatings. <Vinylpyrrolidone/Vinyl Acetate Copolymer> Can also be used as a binder for coatings that adhere to glass, plastic, and metal. <Vinylpyrrolidone/Styrene Copolymer> Produces a clear thermoplastic film that easily adheres to glass, plastic, and metal, and can also be used for hydrophobic coatings and oil-resistant coatings. *For more details, please refer to the PDF document or feel free to contact us.
