Product name: Povidone K90 (PVP K90)
Description
Povidone K90 is a white or yellowish-white powder. When the povidone is heated to 150 ° C, the color will become darker and the water solubility will decrease. Stable at a short time in the range of 110~130 °C; the aqueous solution does not change its properties after steam sterilization.
Application
Povidone (PVP) is widely used in industrial and high-tech fields, and can be used as a surface coating agent, dispersant, thickener and adhesive in pigments, printing, ink, textile printing and dyeing, and in color cathode tubes. It can improve the bonding performance of adhesives to metals, glass, plastics, etc. In addition, PVP is used in emerging high-tech fields such as separation membranes, medical polymer materials, photo-curing resins, photo-curing coatings, optical fibers, and laser discs. PVP-K90 is also widely used in the cosmetics industry. It is very suitable for shampoo, hair care, beauty skin care, hair dye, shampoo, lipstick, sunscreen, toothpaste, etc.
