Jiangsu Sanmu Chemical Co., Ltd.

As the core manufacturing subsidiary of Jiangsu Sanmu Group, Jiangsu Sanmu Chemical Co., Ltd. is a specialized large-scale chemical producer based in Guanlin Industrial Park, Yixing, Jiangsu Province. As the primary production carrier for the group’s epoxy resin and fine chemical product lines, the company focuses on R&D, large-scale manufacturing and precision quality control of epoxy resin products, and has grown into a pivotal professional supplier in China’s epoxy resin sector. Leveraging the group’s full industrial chain support, Sanmu Chemical stands out for its lean production, technological iteration and green manufacturing practices, continuously driving high-quality development across the downstream industrial chain.

I. Large-Scale Production Base with Lean Quality Governance

Jiangsu Sanmu Chemical operates the group’s core epoxy resin production hub, which delivers the majority of the group’s total 350,000-ton annual epoxy resin capacity. The base is equipped with advanced continuous production lines and full-process automated control systems, enabling intelligent monitoring across raw material feeding, reaction processing, finished product separation and packaging. This setup effectively reduces manual deviations and guarantees consistent product performance across batches.

The company has built a rigorous full-cycle quality management system certified by ISO 9001 and ISO 14001 standards. From incoming raw material inspection, intermediate process parameter regulation to finished product performance testing, every stage undergoes multi-dimensional verification covering purity, epoxy value, viscosity and corrosion resistance. This strict quality control framework ensures its products meet the stringent requirements of high-end downstream sectors such as electronic information and new energy, and maintains an industry-leading low defect rate in long-term supply to domestic and global customers.

II. Technological Iteration Fuels High-End Product Breakthroughs

Backed by the group’s provincial-level R&D platforms and its own on-site technical team, Sanmu Chemical focuses on process optimization and high-value product development for epoxy resins, forming a closed-loop system integrating production, research and application. For general-purpose bisphenol A epoxy resins, the company has upgraded synthesis and separation technologies, significantly improving product yield while cutting unit energy and raw material consumption, building up both cost and quality advantages in the mass product market.

In the special epoxy resin segment, Sanmu Chemical has achieved large-scale production of multiple high-performance varieties through independently developed manufacturing processes. Its rosin-modified epoxy resin and o-cresol novolac epoxy resin boast outstanding thermal stability, electrical insulation and mechanical strength, and are widely adopted in electronic packaging, high-temperature resistant coatings and wind power structural materials. The company holds multiple invention patents for epoxy resin preparation and processing, and has driven domestic substitution of several high-end epoxy products that previously relied on imports, breaking technical barriers set by international manufacturers in niche tracks.

III. Green Manufacturing System Leads Industry Low-Carbon Transition

Distinguishing itself from the group’s macro industrial layout, Sanmu Chemical takes green and low-carbon manufacturing as its core competitive edge in production. The company has passed national clean production audits, and established a circular production system covering by-product recovery, waste heat utilization and reclaimed water reuse. It has invested in cutting-edge waste gas and wastewater treatment facilities, implemented full-process VOCs control, and steadily reduced pollutant emissions and carbon intensity per unit of output.

In alignment with China’s dual carbon goals, the company has carried out energy-saving retrofits of production equipment and promoted low-carbon process applications, realizing recycling of by-products generated during epoxy resin production. This practice not only eases environmental pressure, but also improves overall production economic efficiency. Its green manufacturing practices have set a benchmark for standardized operation of epoxy resin manufacturers in the region, and underpin the group’s overall sustainable development strategy.

IV. Deep Market Penetration in Global Segmented Sectors

Supported by stable product quality and reliable supply capacity, Sanmu Chemical’s epoxy resin products have deeply penetrated segmented downstream markets including industrial anti-corrosion coatings, electronic packaging materials, wind turbine blade composites and electrical insulation materials. Its general coating-grade epoxy resin maintains a leading market share in East China, while its electronic-grade and wind power-grade special products have passed supplier certification of numerous leading domestic and foreign enterprises.

In the global market, the company’s products comply with international standards such as REACH and RoHS, and are exported to over 40 countries and regions across Southeast Asia, Europe, the Americas and the Middle East. As the group’s core production and supply entity, Sanmu Chemical supports the group’s global marketing network with efficient delivery and consistent quality, and has forged long-term partnerships with many well-known coating, electronics and new energy enterprises worldwide.

Looking forward, Jiangsu Sanmu Chemical will continue to focus on its core epoxy resin business, further advance intelligent production line transformation and R&D of high-performance special resins, deepen green low-carbon manufacturing practices, and strive to build a world-class professional epoxy resin manufacturer, delivering high-quality, reliable and sustainable material solutions for global downstream industries.
