Polyvinyl Alcohol Resin (Food And Cosmetic Grade) Application: Gule Production

Polyvinyl Alcohol (PVA, sometimes referred to as PVOH, PVAL, CAS no. 9002-89-5) is an excellent water-based adhesive. The general
product is flake, granular or flocculent. It is not easily soluble in cold water. Heating is generally required during
dissolution. After being finely pulverized and surface treated, it has better cold water dissolving performance. But because of
its thermoplasticity, pulverization becomes particularly difficult. Our factory adopts a special liquid nitrogen low temperature
cooling process to ensure that the powder of the crushed material is uniform. So that the material has excellent water solubility.
Polyvinyl Alcohol is classified into two groups, depending on the degree of its hydrolysis, one is fully hydrolyzed, and the other is partially hydrolyzed. Hydrolysis levels from 87% to more than 99%.

Polyvinyl Alcohol is odorless, tasteless, translucent, white or cream colored granular powder, it has substantial tensile
strength, more flexibility, chemical resistance, water solubility, excellent film forming, biodegradability, stability to
temperature variation, non-toxicity, resistance to organic solvents.

Feature:
Good film formation, adhesion, solvent resistance, friction resistance and tensile strength.
Appearance: White solid powder
Melting point:180-190A C
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.

Application:
1. wood, paper, leather, and other aspects of the fiber adhesive (known as latex, white glue) and especially in wood area;
2.As cement additives, and can be used in indoor floor, warships deck, etc.; Mortar, putty powder, coating, interface agent,
decorative plaster, tile jointing agent, silicon nitride and other industrial ceramic powder bonding, cement, gypsum additives,
etc.
3.Also used to wipe wall, waterproof, repair the road surface, etc.
4.The fabric is mainly used for processing dull color. gives processing, printing and dyeing, flocking adhesion, etc.
