PVA is widely used in textile, paper, construction, adhesives, ceramics, packaging, daily chemical and polymer modification and other industries.

In the textile industry, PVA is used as a slurry, which can improve the strength and wear resistance of yarns and effectively improve weaving efficiency. In the field of construction and cement additives, PVA can enhance the flexibility and adhesion of mortar and improve the cracking resistance. In the field of adhesives, PVA is an environmentally friendly adhesive material, suitable for bonding paper, wood, leather and other materials. In addition, PVA can also be used as papermaking enhancer, photosensitive material, film forming agent, etc., and has extensive development potential in the field of polymer functional materials.

PVA has different polymerization degrees and alcoholysis degrees, and can provide products with different properties according to the application needs, such as high viscosity, high strength, fast dissolution, etc., to meet the needs of customers in different process conditions. Its degradable, pollution-free characteristics also make it one of the representatives of environmentally friendly materials, in line with the needs of modern industry for green and sustainable raw materials.

Whether in traditional industries or emerging fields, PVA continues to be recognized by the industry for its outstanding comprehensive performance and applicability, and is an integral part of a wide range of functional products and high-performance materials.

PVA (polyvinyl alcohol) industry application

PVA (Polyvinyl alcohol) is a multi-functional water-soluble polymer material, widely used in many industries, with excellent physical and chemical properties, such as film formation, emulsification, adhesion and degradability. The following are the specific applications of PVA in various industries:

1. Textile industry

In the textile industry, PVA is widely used in the sizing process of yarns. It can enhance the strength and wear resistance of the yarn, improve weaving performance, reduce wear, and thus improve production efficiency. PVA is also often used as a fiber treatment agent to improve the softness and durability of fabrics. In addition, PVA solution also plays an auxiliary role in the dyeing and printing process of fabrics.

2. Paper industry

In the paper industry, PVA is used as a toughening agent and paper coating material to improve the tensile strength, toughness and water resistance of paper. It can also improve the surface gloss of the paper, making the printing quality higher. PVA is also commonly used as an adhesive in the paper making process to enhance the firmness and durability of paper.

3. Construction industry

In the construction industry, PVA is used as a modifier of cement and mortar, which can effectively improve the adhesion, crack resistance and freeze resistance of cement mortar. It can also be used as a strengthening material for concrete, increasing its strength and toughness, making the building material more durable. PVA can also be used to improve the quality of gypsum and paint and enhance the adhesion and durability of coatings.

4. Adhesive industry

PVA is an important environmental adhesive material, widely used in paper, wood, leather, ceramics and other bonding. In the fields of furniture, construction, packaging materials and book binding, PVA adhesives are widely used because of their high efficiency, non-toxic and water-soluble properties.

5. Packaging industry

PVA is used in the production of soluble packaging materials, which can produce packaging bags with fast solubility and environmental protection characteristics. For example, PVA is used to make water-soluble washing bags, fertilizer bags, etc., which can quickly dissolve in water and reduce environmental pollution.

6. Pharmaceutical and daily chemical industries

In the pharmaceutical and daily chemical industry, PVA is commonly used in pharmaceutical film coating, the outer coating material of tablets, and the emulsifier in the pharmaceutical process. It can also be used as a film forming agent and emulsifier in skin care products and washing products to improve the texture and performance of products.

7. Environmental protection and water treatment

PVA is used as a flocculant and precipitator in the water treatment industry to effectively remove suspended solids and harmful substances from water. It can also be used in environmental protection related applications as a water-soluble membrane material to treat wastewater and other hazardous substances.

8. Electronics and optoelectronics

PVA is used in packaging materials and optoelectronic components in the electronics field. It is used as a packaging material for liquid crystal displays (LCD) and solar panels, because of its transparency and good electrical insulation, so that it has been widely used in high-tech fields.

Due to its versatility and environmental protection characteristics, PVA has shown strong application potential in many industries, and with the continuous progress of technology, the application scope and market demand of PVA are still expanding.
