Factory Supply CAS 9003-39-8 Polyvinylpyrrolidone Pvp USP/Ep/Bp Pvp K17 / Pvp K25 / Pvp K30 / Pvp K60 / Pvp K90

In order to serve our customers more effectively, we can also develop individual Polyvinylpyrrolidone K-90, Pvp K 90 Powder, Polyvinylpyrrolidone for our customers according to their needs. We adhere to the company's values ??and fulfill our duties to realize our common pursuit. In the fiercely competitive domestic and foreign markets, we always aim to build a global strategy, and actively promote technology and quality innovation with a higher structure.

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.

With our advanced equipment and exquisite workmanship, we focus on the development and production of Factory Supply CAS 9003-39-8 Polyvinylpyrrolidone Pvp USP/Ep/Bp Pvp K17 / Pvp K25 / Pvp K30 / Pvp K60 / Pvp K90 through continuous practice and innovation. Our company has a superb R&D team, advanced testing equipment, perfect quality management system and good after-sales service. We will continue to focus on the research of intelligent ecological information technology and industry technology to quickly respond to customer needs.
