PVA 2699 has good viscosity, film formation, oil resistance, colloid protection, and biodegradability.
Applications of pva:
1. Adhesive: Good adhesion, when used in combination with clay, it can increase the initial adhesion and accelerate the drying speed, the quality will not change over time.
2. Fiber slurry: Good film forming performance, with soft and strong tensile resistance and elasticity. It is also characterized by resistance to friction, adhesion, smoothness, and good feather effect. And compared to starch slurry, there is no need to worry about spoilage, and enzymatic transformation is also rare.
3. Paper industry: It can be used for surface coating and polishing, significantly improving ester resistance, solvent resistance, and water resistance, and producing higher fabric strength. It can also be used as an adhesive in paint systems and as a carrier for optical polishing agents.
4. Polymerization agent: used as an effective dispersant or stabilizer. They are mainly used as protective colloids and can enhance emulsification at very low concentrations.
5. Poly vinyl alcohol uses in many other industrial applications, such as ceramics, water-soluble membranes, peelable coatings, and temporary adhesives for nonwovens. These products can also be used in various building materials, such as putty, plaster and pva concrete.
6. For textile, PVA is mainly used for sizing pure polyester or polyester cotton yarn, with good adhesion and film-forming properties.
This product is only used for industrial purposes and cannot be consumed.
