PVP K30(9003-39-8)
Product Description
● PVP-K30 is a nonionic polymer compound, inova yakanaka makemikari marudzi ane zvakadzama uye yakafara tsvakurudzo muN-vinyl amide polymers, apo K kukosha chaizvoizvo hunhu ukoshi chokuita hama viscosity PVP aqueous solution.
● PVP K30 yakagadziridzwa kuita nhevedzano yehomopolymers, copolymers uye cross-linked polymers muzvikamu zvitatu: nonionic, cationic uye anionic, uye zvitatu zvinotsanangurwa: giredhi reindasitiri, giredhi remishonga uye giredhi rekudya, ine hukama hwemamolecular masheji kubva kuzviuru zvakati kusvika vanopfuura miriyoni imwe.
