Temperature: Store VAE emulsion in a cool and stable temperature environment. Avoid exposure to extreme temperatures, both high and low, as this can affect the stability of the emulsion. Generally, a temperature range of 5°C to 30°C (41°F to 86°F) is recommended. 2.Avoid Freezing: Protect VAE emulsion from freezing temperatures. Freezing can lead to irreversible changes in the emulsion's structure, resulting in a loss of performance. If the emulsion has been exposed to freezing conditions, it is advisable to thoroughly mix and test it before use. 3.Containers: Store VAE emulsion in tightly sealed containers to prevent air exposure. This helps to avoid evaporation of water and maintains the stability of the emulsion. Ensure that containers are kept in an upright position to prevent leakage and contamination. 4.Ventilation: Store VAE emulsion in a well-ventilated area to prevent the buildup of heat and humidity. Adequate ventilation helps maintain the quality of the emulsion over time. 5.Protection from Sunlight: Shield VAE emulsion from direct sunlight or ultraviolet (UV) radiation. Prolonged exposure to sunlight can potentially degrade the polymer and impact the emulsion's performance. 6.Avoid Contamination: Prevent contamination by using clean equipment and tools when handling or transferring the emulsion. Contaminants can affect the properties of the emulsion. 7.Regular Inspection: Periodically inspect stored VAE emulsion for any signs of separation, coagulation, or other abnormalities. If any issues are identified, investigate the cause and take corrective action as needed. 8.First In, First Out (FIFO): Use a first-in, first-out system to ensure that older batches of VAE emulsion are used before newer ones. This helps prevent extended storage periods and maintains product freshness. 9.ElephChem's Recommendations: Always refer to the specific recommendations provided by the ElephChem for the storage and handling of the particular VAE copolymer emulsion you are using. Different formulations may have specific requirements.

  • Phenolic Resin Industry Development Overview
    Phenolic Resin Industry Development Overview

    1. Phenolic Resin Overview Phenolic resin is a general term for resinous polymers formed by the condensation of phenol and aldehyde in the presence of an acidic or alkaline catalyst. It typically refers to resins obtained by the condensation of phenol or its homologues (such as cresol and xylenol) with formaldehyde. Phenolic resins offer excellent heat resistance, flame resistance, water resistance, and insulation properties. They are widely used in a wide range of applications, including phenolic molding compounds, woodworking and laminates, abrasive and friction materials, and fire-resistant and thermal insulation materials.   2. Phenolic Resin Production Capacity and Output Steadily Rising In recent years, driven by downstream demand and relevant policies, my country's phenolic resin industry has developed relatively steadily, with both production capacity and output showing a steady upward trend. Data shows that production capacity, primarily in East China and Central China, will increase from 1.3 million tons in 2016 to 2.1524 million tons in 2022. Production will also increase from 1.036 million tons in 2016 to 1.535 million tons in 2022. Currently, my country's phenolic resin industry still faces a phenomenon of "overcapacity at the low end and insufficient supply of high-end products," leaving significant room for domestic production of high-end products.     3. Phenolic molding compounds are the largest downstream demand segment for phenolic resins Based on their purity, phenolic resins can be divided into two categories: electronic grade phenolic resin and industrial-grade phenolic resins. Industrial-grade phenolic resins are primarily used in phenolic molding compounds, wood processing and laminates, abrasive and friction materials, and refractory materials. End-use applications include automotive, construction, metallurgy, and rail transportation. Electronic-grade phenolic resins are high-performance, high-value-added phenolic resins, primarily used in chip photoresists, electronic packaging, and copper-clad laminates. End-use applications include semiconductors, aerospace, and consumer electronics. Among them, phenolic molding compounds, grinding and friction materials, and wood processing and laminates are the three downstream application areas of phenolic resin in my country. Their market shares have remained relatively stable in recent years, reaching 21.94%, 20.17%, and 20.01% in 2021, respectively.     In recent years, my country's downstream phenolic resin industry has developed well overall, with demand for phenolic resin steadily increasing, from 1.0423 million tons in 2016 to 1.5423 million tons in 2021. It is worth noting that due to the high technical barriers to electronic-grade phenolic resin, only a few companies in China can currently produce it. Supply currently cannot meet domestic market demand, and imports are needed to supplement it.   4. The import value and average import price of phenolic resin have consistently exceeded the export value and average export price Data shows that in recent years, my country has imported over 80,000 tons of phenolic resin annually, primarily high-end phenolic resin, reaching 86,000 tons in 2023, a slight year-on-year increase of 0.94%. Exports have remained above 90,000 tons, reaching 125,100 tons in 2023, an 18.69% year-on-year increase. Due to the high added value of high-end phenolic resins, my country's import volume and average import price of phenolic resins have always been higher than its export volume and average export price. Data shows that since 2021, its import volume has declined year by year, but its export volume has shown an annual growth trend, reaching 2.045 billion yuan and 1.542 billion yuan in 2023, respectively, a year-on-year decrease of 7.76% and an increase of 10.94%, respectively. With the decline in import volume of phenolic resins and the increase in export volume, its trade deficit has shown a shrinking trend since 2021, falling to 503 million yuan in 2023.     Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com   ElephChem Holding Limited, professional market expert in Phenolic resin and Polyvinyl Alcohol(PVA) with strong recognition and excellent plant facilities of international standards.

  • China's VAE Emulsion Industry: Capacity, Trade, and Revenue Trends in 2025
    China's VAE Emulsion Industry: Capacity, Trade, and Revenue Trends in 2025

    Changes in China's VAE emulsion production capacity are largely due to new construction and expansion projects in the industry. For example, the launch of a 20,000-ton annual VAE commercial emulsion expansion project in Jiangsu and Celanese's announcement to expand emulsion production capacity in Nanjing, China, have been significant. China is a key producer of VAE emulsions around the world, supported by many producers and production lines. Recently, the total production capacity for VAE emulsions has grown, due to increased market needs and better technology. Generally, China's VAE emulsion industry uses its capacity well, especially in areas that need a lot of adhesives and exterior building insulation. In these fields, production lines often run at their maximum.     In 2023, East China, especially Jiangsu and Anhui, became the country's top area for making VAE emulsion. They made 620,000 tons a year, which is over half (56.88%) of all of China's production. Jiangsu did the most, producing 560,000 tons each year, accounting for 51.38% of the country’s total.     China is a big maker and seller of VAE emulsions, and its sales to other countries have been going up. They mostly sell to Southeast Asia, Europe, and North America. Because they don't cost too much and are good quality, Chinese VAE emulsions are becoming important in the world market. Chinese companies are getting better at research, so they can now make many kinds of strong, special VAE emulsions, which means they don't need to buy as much from other countries. The better quality of VAE emulsions made in China means they can do many things, so China bought way less from other countries in 2021. As the industry gets better, they sell more and more to other countries each year.     China's VAE emulsion import market is highly concentrated. Demand is growing and supply chain stability is gradually increasing. In 2023, Taiwan was the largest source of VAE emulsion imports, with imports reaching 27,699.13 tons, accounting for 47.06% of total imports, a year-on-year increase of approximately 35.54%. Singapore was second, with imports reaching 26,329.13 tons, accounting for 44.74% of total imports, a year-on-year increase of approximately 18.47%.     Looking at the apparent consumption of China's VAE emulsion industry, from 2016 to 2021, the industry showed steady growth, driven by downstream demand. In 2022, due to a significant decline in production and imports, apparent demand fluctuated, falling from 791,600 tons in 2021 to 661,700 tons, a year-on-year decrease of 16.41%. Although apparent consumption rebounded in 2023, overall volatility remained significant. The self-sufficiency rate went up in 2022 and 2023, but consumption seemed to drop in 2022. Experts believe that this difference between production and demand changes could cause too much or too little inventory, which would change how supply and demand work in the market.   This article is excerpted from "Analysis of the Current Development Status of China's VAE Emulsion Industry in 2023: The Launch of Jiangsu's 20,000-Ton Annual VAE Commercial Emulsion Expansion Project Will Drive Further Capacity Expansion in the Industry."   Based on market share by production capacity, the competitive landscape in China's VAE emulsion industry is relatively concentrated. Wacker Chemie (China) Co., Ltd. holds the largest market share, at 18.35%. The remaining shares are similar for the remaining companies. The remaining 15.59% of the market share is held by other companies. This indicates that the market is primarily dominated by a few large companies, but there is also some market fragmentation, with other companies collectively sharing approximately one-sixth of the market share.   Wanwei High-Tech Materials Co., Ltd. is a company primarily engaged in the research, development, production, and sales of new chemical materials. The VAE emulsion sector is a core part of the company's business. Its VAE emulsion products serve many purposes, mainly in adhesives, coatings, building materials, and textiles. Wanwei High-Tech has good production methods and tools, so it can make quality VAE emulsions that fit different customer needs. In 2023, the company made about 475 million yuan in revenue from VAE emulsions.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com   ElephChem Holding Limited, professional market expert in VAE Emulsion and Polyvinyl Alcohol(PVA) with strong recognition and excellent plant facilities of international standards.

    The demand for PVB in the domestic construction and automotive fields is promising

    In terms of architectural laminated glass, the National Development and Reform Commission's "Several Opinions on Promoting the Structural Adjustment of the Flat Glass Industry" requires "continuously increasing the proportion of self-used deep-processed glass, promoting the promotion and application of energy-saving glass products, solar energy industry glass, etc." With the continuous development of the construction industry and policy guidance, the domestic green and energy-saving glass product application market is expected to continue to expand, and Polyvinyl Butyral Resin (PVB) laminated glass is expected to continue to grow in demand due to its advantages in safety, energy saving, sound insulation, and environmental protection.     Data from the National Bureau of Statistics shows that in 2021, the production of laminated glass in the country reached 132 million square meters, which is a 15% increase from the previous year. From 2017 to 2021, it grew at an average rate of around 8% each year. In recent years, it has maintained an overall growth trend. It is estimated that by 25, the demand for Polyvinyl Butyral Film (PVB film) in the field of architectural laminated glass will reach about 195,000 tons, an increase of about 55,000 tons from the end of 20.   The demand for PVB film in the automotive glass field comes from the demand for glass replacement of existing vehicles and the installation demand of new vehicles. According to data from the National Bureau of Statistics, the number of domestic cars in 2021 and the number of cars produced were approximately 302 million and 26.28 million, respectively, up 7.5% and 3.8% year-on-year. At present, the front windshield of cars has higher requirements for glass safety performance. Most PVB films are used in the front windshield field. Each car windshield needs about 1.021 tons of PVB film. If the compound growth rate of car ownership from 2022 to 2025 is 4.5% and the annual replacement rate of the front windshield of the existing vehicles is 5%, the demand for PVB film in the domestic automotive field will be about 59,000 tons by 2025, an increase of about 20,000 tons from the end of 2020.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com   ElephChem Holding Limited, professional market expert in Polyvinyl Butyral (PVB) and Polyvinyl Alcohol(PVA) with strong recognition and excellent plant facilities of international standards.
