PVPVA Description

Different proportion of Vinylpyrrolidone to vinylacetate can be offered in powder, alcohol solution and aqueous solution products. The aqueous solution product may be varied from transparent to cloudy. The clarity of the solution depends on the proportion of Vinylpyrrolidone to vinylacetate. The solution is slight acidic but not electrolytic.

PVPVA Application

Cosmetic: PVP/VA Series play a good role in film-former and haifixing agent. Its hygroscopicity decreases with theincrease of the proportion of vinylacetate in the molecular. This property of PVP/VA is extremely useful as it works in hair sprays and hairset lotion. If it is mixed with PVP K30, the effect of hafixing would be changed a lot.

Pharmaceuticals:It is mainly used as water soluble and drying adhesive agent when making grain and pressing tablet directly. It will be used in film coating and covertaste agent. It can prevent sugar coating from

split and make bottom coating avoid dampness.

Other Utility: PVP/VA series can be used in remoistenable adhesive and other adhesives for paper or viscosity-enchancing agent and protecting colloid for printing ink. PVP/VA 64 series can also act as emulsifying agent, protecting colloid forplanting-protecting chemicals, other dispersing systems and binder in coating.
