Panoramic analysis of EVM rubber industry

Thread Content

Panoramic analysis of EVM rubber industry EVM (ethylene-vinyl acetate copolymer rubber) is a special elastomer formed by high-pressure copolymerization of ethylene and vinyl acetate (VA). When the VA content exceeds 40%, the material changes from thermoplastic (EVA) to thermosetting rubber (EVM), forming a unique structure of a saturated main chain plus polar side groups. 1. Excellent heat aging resistance, can be used for a long time at 150℃, the maximum working temperature can reach 175℃ ； 2. Excellent flame retardant performance. The oxygen index of halogen-free flame retardant EVM rubber can reach 38-42, and the combustion smoke is low, slightly corrosive, and the combustion gas is non-toxic. ； 3. Good oil resistance, equivalent to nitrile rubber with an acrylonitrile content of 26%-34%. 4. The disadvantages of EVM are poor water resistance, low viscosity, easy to stick to the roller during processing, and can only be vulcanized with peroxide. 2. Market application: The global EVM market size in 2025 will be approximately US$680 million, with an output of 124,000 tons. ； It is expected to reach US$926 million in 2032, with a CAGR of approximately 4.5% from 2025 to 2032. The industry's gross profit margin remains around 28%, and the annual production capacity of a single line is usually 8,000-10,000 tons/year. Downstream demand is concentrated in three major areas: 1. Consumer goods: Covering household appliances, shoe materials, daily necessities, etc. 2. Industrial components: Mainly including high temperature resistant cable sheaths, industrial hoses, rubber rollers, etc. 3. New energy: Involving power battery sealing, charging interface protection, photovoltaic packaging film, etc. 4. Others: EVM cables are used in rail transit, etc. 3. Production process and technology sources 1. The mainstream process is high-pressure free radical polymerization: Ethylene and vinyl acetate are copolymerized under high temperature and pressure. According to industry data, the synthesis process barriers of EVM are mainly reflected in aspects such as polymerization formula, pressure control and stability control. 2. Overseas technology: For a long time, the EVM market has been dominated by ARLANXEO, and its brand has long occupied the high-end market. A new generation of products has also been developed that incorporates epoxy functionality, allowing it to be cured via non-peroxide cross-linking systems without the need for post-curing. 3. Domestic breakthrough: Local companies represented by Yunnan Zhengbang Technology have made major breakthroughs in EVM synthesis technology and have begun mass production and sales of EVM rubber. At the same time, Sinopec et al. * * The team is also actively deploying patented technologies. 4. Major Manufacturers and Production Capacity In 2025, global EVM production capacity will exceed 120,000 tons, with overseas accounting for more than 85%. 1. Major overseas manufacturers: ARLANXEO (market share exceeds 40%, with production capacity in Germany and the United States), Celanese, Dow, ExxonMobil, LG Chem, etc., accounting for more than 70% in total. 2. Domestic manufacturers: Yunnan Zhengbang Technology: Currently, the only large-scale mass production enterprise in China has formed a production capacity of 10,000 tons, and is the pioneer of domestic substitution. Sinopec: The planned 20,000 tons/year project is in the early stage and is expected to be gradually released in 2028. 5. Capacity Planning 1. Global Pattern: Overseas companies focus on high-end product iterations and have no plans to expand production on a large scale ； The annual growth rate of production capacity from 2025 to 2032 is about 3%, and the tight balance between supply and demand continues. 2. China’s production expansion: Yunnan Zhengbang Technology: Plans to expand to 30,000 tons/year from 2026 to 2028, focusing on new energy and high-end industrial fields Sinopec: The 20,000 tons/year project relies on the advantages of refining and chemical integration to reduce costs and is expected to be put into production before 2028. 6. Market Supply and Demand Supply Side: Global production in 2025 will be 124,000 tons. China's domestic self-sufficiency rate is less than 15%, and import dependence is still high. demand side: In 2025, China's new energy vehicle production and sales will reach 16.63 million and 16.49 million respectively, a year-on-year increase of 29% and 28.2%. Global demand in 2025 will be approximately 128,000 tons, leaving a supply and demand gap of approximately 4,000 tons. price and profit: The global average price is US$5,500/ton, and the industry’s gross profit margin is approximately 28%. New energy drivers: As the voltage of the high-voltage platform of electric vehicles moves from 400V to 800V or even higher, the advantages of EVM in halogen-free flame retardancy and high temperature resistance become more prominent, and demand is expected to further expand. 7. Product profit industry as a whole: Technical barriers and a tight balance between supply and demand support high gross profits, and overseas companies rely on technology monopoly to maintain premiums. Domestic advantages: Domestic companies rely on low-cost raw materials (ethylene/VA) and localized production, with costs 20%–25% lower than imported ones. Gross profit margins can reach 35%–40%, which is 7–12% higher than overseas companies. high-end products: High value-added products such as new energy power battery sealing grades can have gross profit margins exceeding 40%, becoming the core profit growth point for domestic enterprises. 8. Industry development trends 1. Domestic substitution is accelerating. The mass production of Yunnan Zhengbang Technology has verified the technical feasibility, and the entry of Sinopec will further promote the localization process. It is estimated that by 2030, the domestic self-sufficiency rate is expected to reach 50%. 2. The demand for new energy explodes. The popularization of high-voltage platforms (400V → 800V) and the continued growth of photovoltaic installed capacity have promoted the iteration of EVM in the direction of high flame retardancy, high insulation, and aging resistance, and the added value of products has continued to increase. 3. Applications continue to expand. Demand in energy storage systems, charging pile facilities, aerospace and other fields is gradually released, opening up long-term growth space for EVM.
