Polyvinyl Alcohol PVA Powder :

Polyvinyl Alcohl PVA Powder :
1. The bonding glue and adhesives: PVA  has good adhesion, when it combined with clay to make the initial adhesion of increased and faster drying. And PVA has good oil resistance and film strength, and the quality of PVA will not change for long.
2. Fiber slurry: PVA has good film-forming properties, soft and resilient tensile strength and elastic characteristics. And it also rich in abrasion resistance, implicated, smoothness, feathers good effect. PVA can be compared with the starch slurry, do not worry about spoilage, moldy conditions rarely occur.
3. Paper industry: PVA can be used for surface coating and polishing, the ester can significantly improve corrosion resistance, water resistance and resistance to solvents, and may have higher fabric strength. Adhesive may also be used in the coating system, the optical carrier as a polishing agent.
4. Polymerization agent: PVA can be used as an effective dispersant or stabilizer. They are mainly used as a protective colloid, and may enhance the emulsification in the case of a very low concentration.
5.Polyvinyl Alcohol may play a role in many other industrial applications, such as a ceramic, water-soluble film, the non-adhesive release coating and temporary fabric. These products can also be used for a variety of building materials, such as putty and plaster. Polyvinyl Alcohol PVA Powder is particularly suitable for building mortar additive, can improve the cement mortar flexibility, water holding capacity, improve the mortar adhesive. In addition, PVA can reduce mortar friction, thereby enhancing the working efficiency and quality, to precent cracking, plastering layer off, increase the adhesive strength and smoothness. PVA is easy to disperse in cold water, can quickly dispersed in water, the viscosity stability in aqueous solution, which can improve the performance of cement mortar.Polyvinyl Alcohl PVA Powder :1.

Product Description of Polyvinyl Alcohol (PVA)

Polyvinyl Alcohol (PVA) is a synthetic water-soluble polymer which is partially hydrolyzed. It contains acetate and hydroxyl functional elements that provide PVA with exceptional properties.

Polyvinyl alcohol (PVA) is not only a water-soluble compound thickener but is an excellent protective colloid. PVA is commonly a chemical additive to mortar and cement.

It works to enhance the fluidity and cohesion of construction materials, and also reduces drying time significantly of the concrete surface. You can easily mix PVA is all types of organic solvents, however the product is not soluble in plant and animal grease or oil.

PVA is designed to improve the functionality of concrete and mortar. It has high tensile strength and is extremely flexible. It is odorless and packed in ready-to-use form.
