  • $16.00


PVOH3099 (Elvanol® 71-30) is a medium viscosity, fully hydrolized grade of polyvinyl alcohol. White, powder, soluble in hot water but insoluble in cold water and common organic solvents. For most applications, PVOH 30-99 prepared in water solutions. On evaporation of water, transparent films are formed which have high tensile strength and tear resistance. The binder characteristics of PVOH grade 30-99 offer excellent adhesion to porous, hydrophilic surfaces.
Used as sizing agent for paper, textile, ceramic fiber,.... Wall paper glue. 
Solution of PVOH may be applied by brush, paint roller or with spray equipment.
Industries: Paper, Adhesives, Personal Care, Oil & Gas, Emulsion, Construction, Textile.

Additional Description

PVOH 30-99 (Elvanol 71-30) is a high molecular weight, medium viscosity, fully (99%)hydrolyzed grade of polyvinyl alcohol that can dissolve in hot water. It offers high tensile strength and tear resistance. White and granular, it is soluble in hot water but insoluble in cold water and common organic solvents. For most applications, PVOH2 is prepared in water solutions. On evaporation of water, transparent films are formed which have high tensile strength and tear resistance. The binder characteristics of PVOH 30-99 offer excellent adhesion to porous, hydrophilic surfaces. PVOH2 offers a combination of excellent film forming and binder characteristics, along with insolubility in cold water and organic solvents.

About the new product codes:
Older product codes for polyvinyl alcohol have not been very descriptive. New product codes start with a code such as PVOH or PVA and followed by two numbers. The first number is the viscosity (of a 4% solution) and the second number is the degree of hydrolization.
In this product (PVOH 30-99), PVOH stands for PolyVinyl Alcohol (OH represents alcohol) and 30 is the viscosity (in a 4% solution) and 99 indicates 99% hydrolized.
