Application


Under the action of acid catalysis, polyvinyl alcohol can be condensed with formaldehyde, butyraldehyde, glyoxal or other aldehydes to produce polyvinyl acetal (such as PVAF, PVB) with stronger water resistance, adhesion and mechanical strength. It is widely used in construction, coatings, adhesives, safety glass lamination and other fields.With the increase of PVA polymerization degree, the acetal viscosity increases.
