Adhesives and Sealants Formulations with Polyvinyl Alcohols (PVOH)

Polyvinyl alcohol appears as a white to cream-colored powder that dissolves in water to form clear solutions with excellent film-forming properties. Key features include exceptional adhesion to cellulosic materials, biodegradability, and excellent film clarity. Polyvinyl alcohol is ideal for paper products, textile sizing, and wood gluing where their environmental profile and user-friendly handling properties are highly valued. 

Market trends show the development of crosslinkable grades with enhanced water resistance, expanding their application range while preserving their environmentally friendly profile and compatibility with recycling processes. Sub-types include fully and partially hydrolyzed types offering different solubility and adhesion characteristics based on the degree of hydrolysis, and copolymerized grades.
