Polyvinyl alcohol is used as pure glue, but can also be used as a thickener in wall paints, paper coatings, and all kinds of other water-based liquids. Polyvinyl alcohol forms a very good adhesive film and is well soluble in water, the adhesion properties are basically good, depending on the bonding process and the materials. It is resistant to many oils, fats and solvents.
PVOH is also used as an additive or modifier in polyvinyl acetate-based adhesives, emulsions and dispersions.
PVOH applications with flat fiber products
- Shipping boxes
- Anti-slip sheets
- Reusable beverage cartons
- Covered books
- Caravan panels
- Car parts and covers
- Cover and bottoms of shipping tubes.
PVOH applications in tube productions
- Composite sleeves
- Paper and textile
- Tape rolls
- Film and metal foil
- Shipping and packaging tubes
- Constructions and tubes
- Special sleeves
Polyvinyl alcohols also used as modifiers for polyvinyl acetate emulsion adhesives.Polyvinyl alcohol adheres very well to cellulose substrates such as paper and wood. PVOH can increase both the tensile strength of the product and the efficiency in your production.
PVOH value - hydrolysis number
PVOH molecular weight and hydrolysis value usually have a major influence on the final properties of the binders. The In emulsion polymers, molecular weight has an effect on viscosity, shear value, adhesion and wet adhesion. The different levels of hydrolysis affect the stability, water resistance and adhesive film properties
Many of these PVOH products are used in textiles, adhesives, paper, construction products and packaging applications.
