Applications:

Technical grade PVP(especially like PVP K30) are being used in Textiles/Fibers,adhesives,coatings/

paintings,laundry/household detergent,inks,ceramics and other hi-tech indusctries.

example:

pvp k30/k17/k15 is very popular in producing hollow fiber membrane,nano film

PVP K90 is hot with glue,hair gel etc.
