PVP K30(9003-39-8)
Product Description
● PVP-K30 yog ib qho nonnionic polymer compound, uas yog ib hom tshuaj zoo nrog kev tshawb fawb tob thiab dav hauv N-vinyl amide polymers, qhov K tus nqi yog qhov tseeb tus yam ntxwv muaj feem cuam tshuam nrog cov txheeb ze viscosity ntawm PVP aqueous tov.
● PVP K30 tau raug tsim los ua cov homopolymers, copolymers thiab cross-linked polymers nyob rau hauv peb pawg: nonionic, cationic thiab anionic, thiab peb specifications: qib industrial, qib tshuaj thiab qib zaub mov, nrog cov txheeb ze molecular pawg xws li ntau txhiab mus rau tshaj ib lab.
