Carboxylated PVA

I. Definition of Carboxylated Polyvinyl Alcohol (CPVA)Carboxylated polyvinyl alcohol（CPVA) is a hydrogen-modified polymer obtained through a carboxylation reaction based on polyvinyl alcohol (PVA，PVA 088-60 & PVA 2688). CPVA  has typically higher solubility and better performance than unmodified PVA.     II. Functions of Carboxylated Polyvinyl Alcohol PlasticizerCPVA can be used as a plasticizer to improve the processing properties and flexibility of plastics. It is often used in the production of soft plastics, coatings, and rubber products. AdhesiveCPVA can act as an adhesive, forming strong bonds between different materials. For example, when used as glue, it can bond materials such as paper, wood, and plastic together. LubricantCPVA can function as a lubricant, reducing friction on contact surfaces and extending the lifespan of materials. It is commonly used in industrial applications such as metalworking, textile manufacturing, and plastic processing. III. Applications of Carboxylated Polyvinyl Alcohol Packaging MaterialsCPVA is used in manufacturing food packaging materials, such as wrapping paper, plastic films, and straws. This polymer is not only safe and environmentally friendly but also provides excellent flexibility and water resistance, offering effective protection for food packaging. Paper CoatingCPVA is used to coat paper, enhancing its strength and water resistance. It is commonly applied in the production of books, magazines, and other paper-based products. Medical FieldCPVA is used to manufacture medical products, such as sutures and artificial cartilage. It has good biocompatibility and poses no adverse effects when in contact with human tissues, ensuring the safety and reliability of medical materials.   ConclusionCarboxylated polyvinyl alcohol is a multifunctional material with applications as a plasticizer, adhesive, and lubricant. It is widely used in packaging materials, paper coatings, and the medical field.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com  

The global consumption structure of polyvinyl alcohol (PVA) is: polymerization assistants account for about 24%, polyvinyl butyral (PVB) accounts for about 15%, adhesives account for about 14%, textile pulp accounts for about 14%, and paper pulp Materials and coatings account for about 10%, and others 23%. The consumption structure of polyvinyl alcohol (PVA) in China is: polymerization assistants account for about 38%, fabric slurries account for about 20%, adhesives account for about 12%, vinylon fibers account for about 11%, papermaking slurries and coatings account for about 8% %, architectural coatings account for about 5%, and others 6%. Polymerization aids, fabric sizing and adhesives are the main downstream consumer markets for polyvinyl alcohol.   In the first half of 2023, the supply and demand of China PVA (PVA 100-27 & PVA 1799) products( were in a weak balance, and prices were running at low levels. The advantages of China PVA variety in supporting a stable market share. With the introduction of new technologies, new processes, and new products, the continuous expansion of new application fields, and the gradual replacement of imported products, new development opportunities have been brought to the domestic polyvinyl alcohol and vinylon industry. However, as various companies increase their export efforts and adopt fierce competition at the low end, and with the adjustment of China's industrial structure, rising wages and other costs, and high environmental protection requirements, some downstream industries, such as the labor-intensive textile industry, have relocated to Southeast Asia, making domestic Demand growth momentum has slowed, foreign consumption has increased, and exports have increased. After more than ten years of competitive integration and optimization, the industry is showing a new pattern of optimized production capacity, increased concentration, stable market varieties, slow growth in market demand, high technical barriers, moderate competition, and innovation-driven development, reaching a new balance between supply and demand. Develop into a benign new business format.   With the rapid development of PVA downstream industries such as PVA optical film, PVB film, polymerization additives, soil improvement, paper adhesives, ceramic adhesives, environmental protection, medicine and cosmetics, the demand for special PVA products is very strong, and Anhui The special PVA products of leading enterprises in the industry represented by ElephChem have developed rapidly, and they have increased their research and development efforts on PVA fiber, PVB resin, PVB film, PVA optical film, redispersible rubber powder and other products. Special varieties of PVA and The production technology of downstream new material products is becoming increasingly mature, filling many gaps in the country. New PVA products are gradually being put on the market, and their market share is also constantly increasing. Common varieties have basically achieved import substitution, and the downstream consumption structure of the domestic PVA industry has been further expanded.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com
