CAS:63148-65-2

  • Overview Polyvinyl butyral(PVB for short) is the product of acid catalysis of polyvinyl alcohol and butyraldehyde. Because PVB molecules contain long branched chains, they have good compliance, low glass transition temperature, and high tensile strength and impact strength. PVB has excellent transparency, good solubility, good light resistance, water resistance, heat resistance, cold resistance and film formation. It has high adhesion to materials such as glass and metal (especially aluminum). Therefore, it has been widely used in the manufacture of laminated safety glass, adhesives, ceramic paper, aluminum foil, electrical materials, FRP products, fabric treatment agents and other fields, and has become an indispensable synthetic resin material.

    Comprehensive analysis of PVA market in China

    After years of development, China's polyvinyl alcohol industry has become the focus of domestic and foreign markets. As of the first half of 2023, the total production capacity of polyvinyl alcohol in mainland China has reached 1.096 million tons (excluding Taiwan), and the actual output is approximately 400,000 tons, showing a large production scale and market share. The concentration of production capacity is high, and some large enterprises such as Wanwei High-tech and Sinopec have occupied a high market share by virtue of their technology, capital and market advantages.   In international trade, China's polyvinyl alcohol industry occupies an important position, mainly exporting. According to data from the General Administration of Customs of China, my country's polyvinyl alcohol exports will reach 195,000 tons in 2022, a year-on-year increase of approximately 15.9%, showing the strong competitiveness of my country's PVA products in the international market. In addition, although import volume has declined, there is still a certain market demand, which may be related to the domestic market demand for high-quality, special PVA products.   The market demand for polyvinyl alcohol in China continues to grow, mainly benefiting from the continuous expansion of downstream application fields. Polymerization aids, fabric sizing and adhesives are the main downstream consumer markets for polyvinyl alcohol. According to the "In-depth Research and Development Strategy Forecast Report on China's Polyvinyl Alcohol Industry from 2024 to 2029" released by the China Industrial Research Institute, polymerization aids account for about 38% of the PVA consumption structure, fabric slurries account for about 20%, and adhesives account for about Accounting for 12%, vinylon fiber accounts for about 11%, paper pulp and coating account for about 8%, and architectural coatings account for about 5%. Changes in demand in these application fields directly affect the market demand and price fluctuations of polyvinyl alcohol.     In addition, the demand for high value-added PVA products in new industries such as photovoltaics, optoelectronics, and medicine continues to increase, and the industry will enter a healthy development stage of transformation and upgrading. High value-added PVA products such as PVB film, PVA water-soluble film, etc. will have greater market potential.   The supply capacity of China's polyvinyl alcohol industry continues to improve, mainly due to the expansion of production capacity and technological innovation. In terms of production capacity layout, domestic PVA companies are mainly concentrated in areas with rich resources or large market potential such as Shanxi, Shaanxi, Liaoning, and Xinjiang, forming a regional competition pattern. At the same time, as environmental protection requirements increase and market competition intensifies, companies need to increase investment in technology research and development and innovation, improve product quality and reduce costs to gain competitive advantages.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com 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.

  • Polyvinyl alcohol market supply and demand gradually become balanced
    Polyvinyl alcohol market supply and demand gradually become balanced

    This week, domestic polyvinyl alcohol prices rose steadily. As of now, on April 23, the benchmark price of polyvinyl alcohol is ¥12266.67/t, which is an increase of 0.27% compared with last week (¥12233.00/t). During the week, the polyvinyl alcohol market was dominated by rigid demand transactions, with average export support. Dealers offered more profits for shipments, and midstream and downstream merchants remained cautious.   Supply side: The vinyl acetate market price fluctuated and fell this week. Currently, the price of acetic acid, the raw material of vinyl acetate, continues to rise. As of April 22, the benchmark price of acetic acid in Business Society is ¥3,450.00/t, which is an increase of 11.29% compared with the beginning of this month (¥3,100.00/t). In the last 10 It rose 6.15% in one day, 10.40% in 15 days, 11.29% in 20 days, and 15.00% in 30 days. The domestic vinyl acetate market price remained stable during the week, with the price range remaining at around ¥6,343/t.   Demand side: Judging from the domestic demand for polyvinyl alcohol, polymerization aids, fabric slurries, adhesives, vinylon fibers, paper slurries and coatings, and architectural coatings products are relatively weak in raw material consumption. Enterprises mainly purchase by order, and the accumulation of raw material inventory is limited. . Production is coming to an end, the demand for raw materials has weakened, and there is no good news for other terminal companies. There will be a small profit margin for polyvinyl alcohol prices in the later period.   On the whole: supply-side support is average, price support sentiment still exists, price-keeping is the main focus, and the mentality of stockholders is acceptable. Most downstream users continue to purchase on demand, and it is expected that the price of polyvinyl alcohol market negotiations will stabilize in the near future.
