Our History
Changshu Diyou New Material Technology Co., Ltd. is a technology-driven enterprise rooted in a rich industrial heritage while looking toward the future. Although we were formally established under our new name in 2024, our technical lineage and management DNA trace back to 1979; for nearly half a century, we have remained dedicated to the R&D and manufacturing of chemical additives and new materials.
1979: Our predecessor, "Changshu Yangtze River Chemical Plant," was founded, marking the beginning of our journey in the chemical industry.
1990s: Renamed as a chemical additives plant, we grew into one of China's leading manufacturers of PVC calcium-zinc stabilizers, with products widely used in high-end sectors such as medical-grade gloves and synthetic leather.
1994: Received a handwritten inscription from Gu Xiulian, then Minister of Chemical Industry-"Revitalize the factory through technology and scale new heights"-marking a pivotal milestone in our technology-led development.
1996: Restructured as "Fa'ai Chemical," we optimized management mechanisms and achieved ISO9001 quality management system certification, steadily maturing our product quality and service systems.
2018: Fa'ai Chemical was renamed "Fa'ai New Material Technology Co., Ltd.," shifting our business focus toward new materials; that same year, we completed a strategic relocation and technological upgrade of our production systems.
2024: Building upon our accumulated technical expertise, production experience, and customer service philosophy, Changshu Diyou New Material Technology Co., Ltd. was formally established, launching a new phase of growth.
We are not a startup beginning from scratch, but a new enterprise with deep-rooted foundations. We have not only preserved nearly five decades of process data, quality control systems, and industry know-how but have also comprehensively modernized our organizational structure, R&D focus, and environmental standards.
Today, we focus on the R&D and application of cutting-edge new materials, committed to serving global customers with cleaner, more efficient, and more sustainable technological solutions. Our core strengths lie in:
Deep technical expertise-derived from hundreds of product formulations and decades of manufacturing experience;
A commitment to quality-rooted in the ISO9001 system and continuous benchmarking against international standards;
Agile innovation-driven by new organizational structures, teams, and mindsets to respond rapidly to market changes.
While our name may change, our unwavering commitment to quality and the pursuit of innovation remains constant. Upholding our founding mission of "strengthening the enterprise through technology," Diyou will leverage new materials and technologies to provide our global partners with increasingly competitive, eco-friendly solutions.
We cherish the experience gained over the years and value every opportunity for future collaboration. We invite you to contact us as we write the next chapter together.
Our Factory
The company's production base is located in Shanghu Town, Changshu City-within the manufacturing cluster of the Yangtze River Delta-benefiting from excellent industrial supporting infrastructure and transportation logistics. The facility covers an area of approximately 12,000 square meters and is equipped with capabilities for raw material processing, mixing and modification, twin-screw extrusion, pelletizing and packaging, performance testing, and injection molding.
The factory operates a comprehensive production workflow for modified engineering plastics, encompassing raw material feeding, mixing and dispersion, melt blending, extrusion, cooling and pelletizing, packaging, and performance testing. The production floor is equipped with dust-free feeding stations, high-speed mixers, extruders, and packaging machines, enabling the modification of materials such as PA, PC, PP, PPS, and TPE to meet specific requirements for flame retardancy, reinforcement, toughening, weather resistance, antistatic properties, and electrical conductivity.
Regarding product testing, the company utilizes equipment such as vertical/horizontal burning testers, dielectric breakdown testers, electronic tensile testers, melt flow rate testers, composite impact testers, glow-wire testers, and UV weathering testers. These enable the comprehensive testing of materials for flame retardancy, electrical properties, mechanical properties, flow characteristics, impact resistance, and weatherability.
To support customer projects involving plastic components, the company also offers precision injection molding and post-processing services. Molding is performed using all-electric and hybrid injection molding machines, complemented by downstream services such as painting, printing, ultrasonic welding, and assembly.
