Zhonglun New Materials High-End BOPP Electronic Film Debuts at Munich Shanghai Electronics Show, Empowering New Energy, AI Computing Power and Other Industries

As emerging industries such as new energy, wind-solar-storage, and artificial intelligence rise rapidly, they continue to impose higher performance requirements on key foundational materials. On July 1, electronica China 2026, known as a bellwether for the global electronics industry, grandly opened in Shanghai. Xiamen Changsu, a member company of Sinolong New Materials Co., Ltd., showcased its high-end BOPP electronic film products, attracting numerous industry customers and professionals for in-depth exchanges. This also marks the first appearance of this product series at a top-tier global electronics exhibition since it entered mass production in November 2025.

Leveraging its strong technological barriers and mature industrialized operational capabilities, Sinolong New Materials is one of the few companies in China capable of large-scale mass production of ultra-thin BOPP electronic film. At this exhibition, the company launched a range of domestically produced high-end BOPP electronic film solutions in multiple specifications from 2.0 μm to 5.8 μm, covering the entire process from material innovation and customized development to mass production and delivery, precisely empowering application scenarios such as new energy vehicles, wind, solar and energy storage, AI data centers, and safety-compliant electronics.

Ultra-thin BOPP electronic film, the “chip” of high-end industrial materials

Currently, the new energy and AI computing power industries are continuously evolving towards high energy density and high safety reliability, and film capacitors are upgrading in the direction of high voltage resistance, high temperature resistance, and ultra-thinness. The performance of capacitors is directly related to the electric drive efficiency of new energy vehicles, the operational stability of photovoltaic inverters, as well as the overall safety of smart grids and data centers. High-end BOPP electronic films, with their excellent voltage resistance, high-temperature stability, and high-frequency adaptability, have become the core substrate for film capacitors and are key materials to ensure the stable operation of power electronic devices.

Zhonglun New Materials has launched a 2.0μm–3.4μm ultra-thin BOPP electronic film, featuring high temperature resistance, high voltage resistance, low dielectric loss, and high self-healing properties. The performance and quality consistency of the product has significantly improved, while the unit energy consumption is lower. This product is suitable for the DC-Link direct support scenarios of 800V/400V platforms in new energy vehicles, providing smooth filtering, absorbing pulsating currents, and suppressing voltage fluctuations to effectively protect power devices. It is widely used in core components such as OBC onboard chargers, DC/DC converters, and charging piles, ensuring the stable operation of the vehicle's electrical control system.

Multi-specification product matrix covering high-growth emerging markets

High-end BOPP electronic film is a key material that determines the performance of film capacitors, and its application scenarios are continuing to expand into high-growth emerging fields. Sinolong New Materials has established a multi-specification product matrix that, in addition to new energy vehicles, can also meet the application needs of various scenarios such as wind, solar, and energy storage, AI servers, and safety capacitors.

In the field of solar, wind, and energy storage, 3.4μm-5.8μm specification BOPP electronic films are suitable for photovoltaic inverters, wind power converters, and energy storage devices. They can smooth DC voltage, stabilize the bus, absorb high-frequency pulses, achieve ripple suppression and energy buffering, and comprehensively enhance the operational efficiency, reliability, and service life of solar, wind, and energy storage equipment.

With the large-scale construction of AI computing power centers, AI servers have become an important incremental market for film capacitors. The company has launched 2.9 μm–5.8 μm BOPP electronic film designed for HVDC data centers, enabling multiple functions such as high-voltage DC support, high-frequency filtering, noise suppression, and electromagnetic interference protection. It meets the high-power and high-stability power supply requirements of AI servers and provides critical material support for computing infrastructure.

In addition, this series of products can be used with X capacitors and Y capacitors to suppress differential mode electromagnetic interference and control common mode interference, ensuring both the electromagnetic safety of the equipment and the safety of personal electrical use, while meeting the stringent requirements for safety capacitors.

High-end production capacity is steadily coming onstream, while high-barrier products continue to drive incremental growth.

From product mass production and batch delivery to widespread market recognition, Zhonglun New Materials has achieved a rapid breakthrough in the high-end BOPP electronic film sector, thanks primarily to years of technological accumulation and mature industrialization and operational capabilities.

The company has been deeply engaged in the new materials sector for many years. It is one of the few companies in the world that have mastered the three core technologies of sequential stretching, mechanical simultaneous stretching, and maglev linear motor simultaneous stretching, and has independently pioneered fifth-generation low-carbon biaxial stretching technology, building a solid technological barrier in material mechanism research, high-end product development, and stretching process innovation.

Zhonglun New Materials plans to establish 9 high-end BOPP production lines for its new energy film project. The first production line was put into operation in November 2025; the second production line is currently under construction and is expected to be operational in the second half of 2026, with the remaining production lines also progressing rapidly. As capacity continues to be released, the company's supply capability for high-end electronic films will be significantly enhanced.

This exhibition marks an important strategic move by Zhonglun New Materials to expand into the high-end electronic film market. Leveraging the exhibition’s full industry-chain resources, the company has established targeted connections with enterprises in fields such as film capacitors, new energy vehicles, photovoltaic inverters, energy storage equipment, and AI server power supplies, laying a solid foundation for deeper future cooperation.

At present, Zhonglun New Materials’ business has expanded to more than 40 countries and regions worldwide, and its products have entered the supply chains of leading downstream enterprises such as CATL, BYD, EVE Energy, Farasis Energy, Sunwoda, Zhuhai CosMX, and Faratronic. Going forward, the company will continue to increase R&D investment, accelerate the release of high-end production capacity, and deepen collaboration across the upstream and downstream value chain, steadily raising the market share of domestically produced high-end film materials and providing key material support for the development of industries such as new energy and digital computing power.
