What is iSuoChem Chemical Properties of Polyvinyl Butyral

Product introduction

English name: Polyvinyl Butyral, PVB resin, Polyvinyl Butyral resin

Polyvinyl butyral resin (PVB), an important invention in the modern chemical field, is meticulously synthesized through the acetal reaction between polyvinyl alcohol (PVA) and butyraldehyde catalyzed by a highly efficient catalyst. This solvent-based resin, with its unique white, round, spherical, porous particle morphology, is the material of choice for many industrial applications.

Chemical Properties

Any chemical that reacts with secondary alcohols will also react with Polyvinyl Butyral. In many applications, Polyvinyl Butyra resin is often combined with thermosetting resins to bridge and harden the hydroxyl groups of Polyvinyl Butyra to achieve chemical, solvent and water resistance. Depending on the type of thermosetting resin used and the mixing ratio between it and polyvinyl butyral resin (PVB), it is possible to formulate a coating film with different characteristics (e.g., hardness, toughness, impact resistance, etc.). This means that by adjusting the ratio and type of these resins, we can customize the coating film to meet the needs of a specific application with the desired chemical properties.
