In addition to improving the quality of our 25655-41-8, Polyvinylpyrrolidone 90, Polyvinylpyrrolidone Iodine, we also need to develop more sales markets. We are advancing at full speed towards a quality and efficiency enterprise, showing our strong strength at all times. The company adheres to the business philosophy of 'Quality First, Honesty First', selects the highest quality and environmentally friendly raw materials, and uses the most modern processing equipment.

Product Description:

This product is obtained by polymerizing pyrrolidone and ethylene to produce vinyl pyrrolidone monomer under pressure and under the action of a catalyst. The 1-vinyl-2-pyrrolidone homopolymer has an average molecular weight of 3.8X104 and the molecular formula is (C6H9NO)n, where n represents the average number of 1-vinyl-2-pyrrolidone chain segments.

Physical properties:

Solubility and solution characteristics

The aqueous solution of PVPK90 is non-thixotropic in most cases and has a short relaxation time. When the concentration is large, it will have a certain structural viscosity: when the shear force is increased, the viscosity will decrease. Controlling the concentration of PVPK90 will bring many different application properties to PVPK90.

The width of the molecular weight distribution and its impact:

Like all free radical polymerization products, PVP has a typical Schulg-Ftory molecular weight distribution. As the high molecular weight PVPK90 in the PVP series, its molecular weight distribution curve is usually wider, because of the higher molecular weight, which usually becomes Many branches. The higher the degree of grafting, the larger the molecular weight and the wider the distribution. The molecular weight distribution of PVPK90 can be controlled well in order to exert its due performance in application, otherwise its performance will be limited and the expected use effect will not be achieved.

Our aim is: to create value for customers, to create interests for customers, to provide customers with cost-effective Pvp K90 Liquid/Pvp K90 20% Solution/CAS No.: 9003-39-8. We operate an intensive channel distribution and service network in the whole industry, which is famous for its consistent close to the market, regional direct sales and customer-oriented services. Relying on complete testing equipment, perfect testing methods, and strict quality standards, we have been committed to improving the quality and performance of our products.
