Application:
PVPK products possess excellent adhesive,film-forming,dispersing and thickening properties,which are widely used in the
pharmaceutical industry.They are one of the three main accessory products recognized & approved worldwide.
General Summarization:Low molecular weight PVPK ,for use as a solubilizing agent,crystallization inhibitor and suspension stabilizer
in injectables and ophthalmic formulations.Such as PVPK12,K15,K17.Medium Molecular PVPK,for use as binder in tablets,capsules and
granulers,as a stabilizer for oral suspensions,film-forming agent,soluilizing agent,dispersant for pigments,as an enzyme stabilizer and
to imrove bioavailability.e.g.PVPK25,K30.High molecular PVPK ,a highly effetive binder,for us as stabilizer in oral and topical suspensions,
as a thickener,hydropilizing agent e.g.PVPK60,K90.
Remarks: PVP is available for Cosmetic/Personal care applications,they are requested subject to special quality and purity controls
of the cosmetic/personal care formulations needed.
Packing and delivery:25kg/bag,8tons/FCL with pallets, 9tons/FCL without pallets.
