About polyvinyl alcohol
Polyvinyl alcohol: properties and applications
Polyvinyl alcohol is a synthetic polymer produced by the hydrolysis of polyvinyl acetate. Common abbreviations are PVA and PVOH. It is used as a film-forming polymer, binder and protective colloid. Its properties depend on the grade, including the degree of hydrolysis and degree of polymerization.
Polyvinyl alcohol should be distinguished from a finished “PVA glue”, a term commonly used for adhesives based on polyvinyl acetate dispersions. PVOH may be used in their production and formulation, but it is not itself a ready-to-use polyvinyl acetate adhesive.
Polyvinyl alcohol grades in the catalog
The REVADA Industrial catalog is organized by manufacturer: Wanwei, Chang Chun Petrochemical, Shuangxin, Dadi, Sinopec Ningxia and Sinopec SVW. The range includes partially and fully hydrolyzed polyvinyl alcohols. The Chang Chun Petrochemical section also includes low-foaming and low-ash grades.
Select a manufacturer to explore the product groups and individual grade specifications. A catalog listing does not confirm current stock: availability, packaging and supply terms should be confirmed when making an enquiry.
How to select a PVOH grade
Degree of hydrolysis
The degree of hydrolysis describes the proportion of acetate groups converted to hydroxyl groups. It influences solubility and performance in a formulation. Partially and fully hydrolyzed grades serve different requirements; a higher degree of hydrolysis does not automatically make a grade more suitable for every adhesive or coating.
Solution viscosity
Compare viscosity values at the same solution concentration, temperature and test method. Several product entries specify the viscosity of a 4% aqueous solution at 20 °C. This is a grade characteristic, not a guaranteed viscosity for the finished formulation, which also depends on concentration, temperature and other ingredients.
Additional requirements
Consider ash content, volatile content, pH, foaming behavior and supplied form where these parameters matter to the process. Grades from different manufacturers should not be treated as interchangeable based on similar names alone. Compare their specifications and evaluate the material in the intended formulation.
Adhesives, dispersions and related applications
In adhesive systems, PVOH is used as a binder and film-forming component. In emulsion polymerization, it can act as a protective colloid. Grade selection should take account of the formulation, substrates, application method and required bond performance.
Polyvinyl alcohol is also used in paper and textile processing. For related requirements, explore our textile industry range and raw materials for coatings and dry building mixes. The suitability of an individual grade depends on the requirements of the specific formulation.
Solution preparation and technical documentation
There is no single dissolution procedure suitable for all polyvinyl alcohol grades. Temperature, concentration, addition sequence and mixing time should follow the manufacturer’s recommendations for the selected product. Preparing an aqueous PVOH solution and producing a polymer dispersion are distinct processes.
Consult the technical specification for processing guidance and the safety data sheet for handling and storage requirements. Suitability for special applications, including food-contact materials, must be confirmed separately for the selected product and intended conditions of use.
Request a quotation for polyvinyl alcohol
Please specify the manufacturer and grade, or the required degree of hydrolysis and solution viscosity. Include the intended application, required quantity and delivery location. When seeking an alternative to an existing material, provide its technical specification.
