Product Description

ZHUOJUN® polyvinyl alcohol powder, also known as ZHUOJUN® PVA, is slightly off-white to beige stable non-toxic water-soluble macro-molecular synthetic polymer, which is made from vinyl acetate through the polymerization and saponification and quickly dissolves in water to form a stable colloid. It exhibits excellent water solubility, bonding strength, film forming properties and chemical stability.

 

Chemical Properties

ZHUOJUN® PVA can be regarded as a linear macro-molecular polymer with a secondary hydroxyl group. The hydroxyl group in the molecular of the PVA powder has high activity and can carry out typical chemical reactions of low alcohols, such as esterification, etherification, acetalization, etc., and can also react with a variety of inorganic or organic compounds.

 

Physical Properties

Performance: odorless and tasteless slightly off-white to beige flowing powder

Solubility: an alcoholy-soluble PVA powder that dissolves in room temperature water.

Thermal Stability: ZHUOJUN® PVA softens when heated, and does not change significantly below 40℃. It will gradually color when heated for a long time at 160 ℃, and decomposes when it is above 220 ℃ to form water, acetic acid, acetaldehyde and crotonaldehyde.

Chemical Resistance: it is almost unaffected by weak acids, weak alkalis or organic solvents and has high oil resistance

Storage Stability: it is a low-viscosity polymer, whose water solubility is stable at room temperature and does not deteriorate during storage.

Film Formation: due to the high adhesion between the PVA powder molecules, the film is easily formed. And the formed film is colorless and transparent, has good mechanical strength, and has a smooth surface without stickiness and good solvent resistance. It has good light transmission, high moisture permeability, good printability with no electricity or no dust.

 

Typical Applications:

- various construction mortar

- dry powder render/putty

- tile adhesive

- gypsum spray plaster binder

 

ZHUOJUN® PVA Advantages:

-Improves bonding strength

-Improves smoothness and surface gloss
-Improves oil resistance and abrasion resistance

-Improve film forming properties and chemical stability
