Discrimination of pvpk30 k90:

The Shore hardness, thickness and impact resistance of K90 after film formation are far stronger than K30. If it is used as a solid content auxiliary material for water-based resin adhesives, K90 has the best water resistance and hardness, please refer to it as appropriate. There are K120 and K150 on the top, but the higher the molecular weight, the higher the viscosity, which is not conducive to the smoothness and spreading of the film.

Application:

Plastic production

In the production of solid plastic polymers, PVPK is added as a protective colloid and polymerization stabilizer.

Adhesive

PVPK 90 and K 85 are thickeners and thickeners for sodium stearate adhesives. Different PVPK can be mixed to get suitable viscosity. In the adhesive dispersion, PVP K is also used as a protective colloid and thickener.

PVP K is also used as a wettable glue for sealing stamps and envelopes because PVP is soluble in water.

Solubility:

Easily soluble in water and solvents containing halogenated hydrocarbons, alcohols, amines, nitroalkanes and low molecular fatty acids, etc., but insoluble in a few solvents such as acetone, ether, turpentine, aliphatic hydrocarbons and alicyclic hydrocarbons. Compatible with most inorganic salts and various resins.

Crosslinked homopolymer of pure vinylpyrrolidone. It has the ability of polyvinylpyrrolidone (PVP) to complex with a variety of substances (such as various glutinous substances that cause the discoloration of beverages such as wine). And because of its insolubility, it is easy to remove after filtration.

Now we are developing towards product diversification, choosing diversified direction, providing customers with a wide range of products and services is our unchangeable standard.After years of development, our Pvp (K15, K17, K25, K30, K90) have a large market share. If you are interested in our products, we look forward to your online message or call us. We will wholeheartedly provide customers with all support and guarantees other than non-core business.
