Tongyu has long been dedicated to electronic resins for copper clad laminate (CCL) production, having developed a well-established product portfolio tailored for lead-free and halogen-free CCL applications. Through sustained investment in research and development (R&D), the company has further expanded its offerings into electronic resins for high-speed and high-frequency CCLs. Today, Tongyu boasts high-efficiency production capabilities, enabling it to manufacture multiple refined grades of products simultaneously. It provides comprehensive resin system solutions specifically for the mid-to-high-end CCL industry, and has earned a strong reputation in the field of lead-free and halogen-free epoxy resin-based CCLs. By continuing to prioritize R&D investment, Tongyu has successfully extended its product range to cover electronic resins designed for high-speed and high-frequency CCL applications, solidifying its position as a reliable partner for the mid-to-high-end CCL sector with its ability to deliver products of diverse specifications efficiently. 1. Mature and diversified product portfolio Through continuous investment in R&D and close collaboration with copper clad laminate manufacturers, Tongyu has developed a mature and diverse product portfolio. Its products range from lead-free and halogen-free copper clad laminate resins suitable for applications across the full spectrum of glass transition temperatures, to those designed for low Dk/Df and high-speed applications. The company’s electronic resin developments keep pace with evolving industry trends, providing downstream copper clad laminate manufacturers with a comprehensive product lineup. This strengthens Tongyu’s market position and supports its ongoing business growth. 2. Comprehensive solutions overcome certification bottlenecks Product certification is a critical market entry barrier in the copper clad laminate industry. In addition to complying with the standards of authoritative certification bodies, Tongyu’s electronic resins must also fulfill the comprehensive certification requirements imposed by downstream and end-device manufacturers regarding all aspects of material performance. These certifications are typically more detailed and stringent, with lengthy approval cycles. By delivering high-quality products and providing professional, systematic electronic resin recommendation services, our company has gained the trust of many renowned downstream copper clad laminate manufacturers. After years of dedicated R&D, Tongyu has achieved certification from major industry players including Jiantao Group, Shengyi Technology, Nanya New Materials, Ultrasonic Electronics, and Huazheng New Materials. This has enabled entry into their supplier networks and the establishment of long-term, stable cooperative partnerships. 3. Tackle core challenges and drive innovation The company focuses in the research, development, production, and sales of electronic resins. Over the years, it has accumulated extensive technical and practical experiences, especially in product applications and production. While R&D direction is market-driven, Tongyu always adheres to technological innovation and self reliance to transform R&D findings into commercialization . Thus the company can be at the forefront of domestic technology and catch up with leading international competitors. Furthermore, the core R&D management team of Tongyu has extensive industry experience and has developed forward-thinking technical expertise to anticipate market developments. Tongyu is one of the few domestic companies to possess core technologies to produce multiple series of lead-free, halogen-free, and high-speed electronic resins. The company is actively achieving the localization of high-end application electronic resins, demonstrating its strong R&D potential. Tongyu has successfully overcome a series of technical challenges of purity control in productions. Examples are the reduction of impurity in DOPO-modified epoxy resins, the low free phenol content in benzoxazine resins, the low free monomer content in phosphorus-containing phenolic resins, the molecular weight and functionality control in polyphenylene ether oxidation reactions, and the copolymerization and grafting synthesis of high-order hydrocarbon resins. The company holds 17 invention patents, and its outstanding R&D performances have laid a solid foundation for its sustainable development for many years to come. The company through the long-term tracking of the OEM market has equipped itself the ability to respond in time to the innovation needs of downstream industries. In addition, Tongyu also accumulates forward-looking technology reserves and is deeply integrated with downstream industry innovation. 4. Quick response and refined customer service Tongyu adopts a direct sales model, directly communicating with copper clad laminating customers, therefore understanding the relationship between terminal performance requirements and electronic resin characteristics。It is obvious that the company’s products can fully align with the market demands of PCB electronics industry very well. Leveraging its local advantages, Tongyu provides refined services to customers and offers systematic solutions for them; regular technical exchanges are conducted among R&D departments to accelerate project R&D progress, shorten project development cycles, advance the progress of customer sample evaluation and small-batch introduction, and realize mass production cooperation as soon as possible. Convenient localized product delivery helps reduce customers’ inventory costs, balance market demand, and mitigate the risks of price fluctuations. Meanwhile, rapid response to quality complaints facilitates timely problem-solving and lowers the cost of quality abnormalities in customers’ assembly line operations. Regular face-to-face technical exchanges among R&D departments help accelerate project progress and shorten project development cycles. Meanwhile, close engagement with end manufacturers facilitates timely and accurate understanding of industry development trends. 5. Efficient and stable continuous production automation The company is equipped with DCS automated control production lines. Leveraging years of technological expertise accumulated by its production and technical teams, Tongyu independently designs, upgrades, and optimizes production lines and supporting facilities while continuously improving production processes. For mature products, the company has consistently enhanced delivery efficiency and now has the manufacturing capability to simultaneously produce and rapidly deliver highly differentiated product series as well as single products in multiple specifications. The production lines feature a high level of automation, ensuring consistent product quality, and are complemented by a complete set of small to medium-scale pilot reaction devices. These enable quick mass production of newly developed products in small and medium batches.This setup allows Tongyu to swiftly support initial certification for new projects and significantly shorten the new product certification cycle.
