Polyvinyl Alcohol (PVA) is a versatile polymer with applications spanning numerous industries, from adhesives and textiles to paper and cosmetics. A critical parameter that dictates PVA's suitability for specific applications is its viscosity, which is directly related to its molecular weight and degree of hydrolysis. NINGBO INNO PHARMCHEM CO.,LTD., a leading PVA manufacturer in China, provides essential insights into understanding PVA viscosity and its implications.

Viscosity in PVA is typically expressed in centipoise (Cps) and is a measure of a polymer solution's resistance to flow. For Polyvinyl Alcohol 1788 (CAS 9002-89-5), the stated viscosity range often falls between 21-26 Cps for a specific concentration and degree of hydrolysis. This medium viscosity is highly desirable for many applications, including its use as an adhesive and in textile sizing. Higher viscosity grades, generally corresponding to higher molecular weights, offer stronger film formation and increased adhesive strength, making them suitable for demanding structural adhesives or heavy-duty textile sizing. Conversely, lower viscosity grades might be preferred for applications requiring easier flow, such as in certain inks or thin coatings.

The degree of hydrolysis also plays a crucial role in determining PVA's final properties, including its viscosity and solubility characteristics. For instance, fully hydrolyzed PVA grades tend to have higher viscosity and better water resistance compared to partially hydrolyzed grades of similar molecular weight. When you buy PVA 1788, understanding these relationships ensures you select a product that meets your formulation's specific rheological and performance needs. As a reliable Polyvinyl Alcohol supplier, we offer detailed technical data for all our grades.

Manufacturers looking to source PVA efficiently should partner with experienced suppliers who can provide accurate viscosity data and application guidance.
