    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 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.

  • The two types of PVA :Fully Hydrolyzed PVA and Partially Hydrolyzed PVA
    Mar 18, 2020
    There are two main types of polyvinyl (PVA) based on the degree of hydrolysis, which refers to the extent to which the vinyl acetate monomers in PVA have been converted to vinyl alcohol units.   Fully Hydrolyzed PVA: This type of PVA has undergone complete hydrolysis of the vinyl acetate units, resulting in a high degree of hydrolysis and a high concentration of vinyl alcohol units. Fully hydrolyzed PVA has excellent water solubility and forms strong and stable films after drying. It is widely used as an adhesive, binder, film-forming agent, and thickener in various industries such as papermaking, textiles, packaging, construction, and personal care products.   Partially Hydrolyzed PVA: Partially hydrolyzed PVA has undergone partial hydrolysis of the vinyl acetate units, resulting in a moderate degree of hydrolysis and a lower concentration of vinyl alcohol units compared to fully hydrolyzed PVA. This type of PVA combines the advantages of both PVA and its precursor, polyvinyl acetate (PVAc). Partially hydrolyzed PVA is commonly used as a protective colloid, emulsion stabilizer, and dispersing agent in the production of adhesives, paints, coatings, and textile printing pastes.   Both fully hydrolyzed PVA and partially hydrolyzed PVA have their specific applications and properties, and their usage depends on the desired characteristics and requirements of the end product in various industries.   Website: Whatsapp: (+)86 13851435272 E-mail: ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards

  • What are the safety precautions for polyvinyl alcohol?
    Mar 10, 2020
    Polyvinyl alcohol (PVA) is generally considered safe for use in various applications, but it is still important to follow proper safety precautions. Here are some general safety guidelines for handling polyvinyl alcohol:   1.Personal Protective Equipment (PPE): Wear appropriate PPE, including gloves, safety goggles, and a lab coat or protective clothing, to prevent direct contact with the skin, eyes, or clothing.   2.Ventilation: Work in a well-ventilated area or use local exhaust ventilation to minimize inhalation of dust or vapors.   3.Handling: Handle PVA with care to avoid spills or releases. Follow proper handling procedures and avoid generating dust or aerosols.   4.Storage: Store PVA in a cool, dry, well-ventilated area away from incompatible substances, such as strong acids or oxidizing agents. Follow any specific storage requirements provided by the manufacturer.   5.Fire Safety: PVA is generally non-flammable, but it can burn under certain conditions. Take standard fire precautions and use appropriate fire-extinguishing methods for surrounding materials if a fire occurs.   6.Disposal: Dispose of PVA waste in accordance with applicable local regulations and guidelines. Follow proper waste management practices to prevent environmental contamination.   It's important to note that specific safety precautions may vary depending on the concentration, form (solid, solution, or film), and intended application of polyvinyl alcohol. Always refer to the safety data sheet (SDS) provided by the manufacturer for detailed information and customized instructions regarding the safe handling, storage, and disposal of PVA.   Website: Whatsapp: (+)86 13851435272 E-mail: ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards

  • Are starch-based adhesives similar to PVA?
    Mar 02, 2020
    Starch-based adhesives and polyvinyl alcohol (PVA) are both commonly used types of adhesives, but they have some differences in their properties and applications.   Starch-based adhesives, as the name suggests, are derived from starch, which is typically sourced from corn, wheat, or other plant materials. These adhesives are natural, renewable, and biodegradable, making them environmentally friendly. Starch-based adhesives are often used in industries such as packaging, woodworking, and paper bonding.   On the other hand, PVA is a synthetic polymer that is water-soluble and known for its adhesive properties. It offers strong bonding strength and good film-forming abilities. PVA adhesives have a wide range of applications, including woodworking, bookbinding, paper packaging, and crafts.   In terms of performance, PVA adhesives generally have higher bonding strength and greater water resistance compared to starch-based adhesives. PVA adhesives also offer better flexibility and can adhere to a variety of materials.   The choice between starch-based adhesives and PVA depends on the specific application requirements and desired properties. Starch-based adhesives are favored for their sustainability and biodegradability, while PVA adhesives are known for their strong adhesion and versatility.     Website: Whatsapp: (+)86 13851435272 E-mail: ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards
