PRODUCT DESCRIPTION

Polyvinyl Alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in PVAc adhesive formulations, in a variety of coatings, and 3D printing. It is colourless (white) and odorless. It is commonly supplied as beads or as solutions in water. Without an externally added crosslinking agent, PVA solution can be gelled through repeated freezing-thawing, yielding highly strong, ultrapure, biocompatible hydrogels which have been used for a variety of applications such as vascular stents, cartilages, contact lenses, etc.. 

 

PRODUCT FEATURES

Good film formation, adhesion, solvent resistance, friction resistance and tensile strength.
Appearance:White solid powder
Melting point:180-190ºC
Size:80-120 mesh

 

Small particles, small dosage, easy to disperse.
Dissolved in cold water.
Good bonding performance; improve mortar strength.
Prevent mortar from cracking and detaching; increase adhesion strength and smoothness.
Non-toxic, tasteless and environmentally friendly.

 

PRODUCT USAGE

1.In the textile industry , they are mainly used as yarn pulp, fabric finishing agents, and raw materials of vinylon fibers;

2. In the construction and decoration industries, they can be used as mortar cement additives, paint additives for interior and exterior walls, and molding plate adhesives;

3. In the chemical industry, they can be used as polymerization emulsifiers, dispersants, and raw materials for the production of PVF, aceta l and butyral resins;

4. In lumbering and paper-making industries, they can be used as adhesives;

5. In agriculture, they can be used as soil improvers, pesticide adhesion synergist and PVA film;

6. In petroleum exploitation, they can be used as well-cementing agents.

7. In addition, they can also be used in cosmetics, pharmaceuticals, printing, ceramics, steel, electronics, electroplating, and so on.
