Alkohol polibinila (PVA) Wanwei
Alkohol polibiniloa (PVA) kutsatzen ez den polimero uretan disolbagarria da, normalean flokulu zuria edo horia arina, maluta, granularra edo hauts solidoa.Bere errendimendua plastikoaren eta kautxuaren artekoa da.Atxikimendu ona, filma sortzeko gaitasuna, isolamendua, olioaren erresistentzia, urradura erresistentzia eta gas hesiaren propietatea, etab.
Produktuen erabilerak
Polibinil alkoholak (PVA) erabilera ugari ditu.
Ehungintzan, deformazio-minda, ehungintza akabera agente eta ehundu gabeko ehunen itsasgarri gisa erabiltzen da.
Eraikuntza-industrian, zementuzko gehigarri gisa erabiltzen da, moldatzeko plaken itsasgarri gisa eta eraikuntza-kolak.
Industria kimikoan, semultsio-egonkortzaileak eta barreiatzaileak erabiltzen dira.
Papergintzako industrian, itsasgarri gisa erabiltzen da.
Horrez gain, kosmetika industrian, nekazaritzan, farmazia industrian, etab. erabil daiteke.
