We deeply realize that only the four aspects of technology, equipment, production process, and high-quality raw materials can be combined to produce perfect products.

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.

Thanks to the trust and support of our customers, our company is also developing rapidly and healthily. Our Pvp K90 Used for Detergent have been exported to many countries and regions. We will continue to strengthen the construction of environmental protection facilities and strive to be the best environmental protection enterprise in the country. We unremittingly improve the comprehensive strength of research and development.
