Xuancheng Juyuan Fine Chemical Co., Ltd. was established in 1990. Since its inception, the company has been dedicated to the production and development of phosphate ester flame retardants, making it one of the earliest companies in China to specialize in the research, production, and development of phosphate ester flame retardants. After two decades of development, by 2011, the company's annual production capacity of phosphate ester flame retardants reached 20,000 tons, forming a flame retardant production system primarily based on halogen-free phosphate ester flame retardants and halogenated phosphate ester flame retardants. Currently, the company's products are mainly exported, with established sales and service networks in the United States, Europe, and the Asia-Pacific region. Thanks to stable product quality and a strong reputation, we have become long-term strategic partners with many world-renowned companies.   The company strictly implements the ISO9001 quality management system, with comprehensive management and supervision systems in place for raw material procurement, product production, and logistics. To enhance the company's technical research and development capabilities, we have established long-term collaborations with renowned domestic universities and research institutes, investing heavily in the updating and maintenance of laboratory equipment.   While focusing on corporate development, the company also upholds its corporate responsibilities and social mission. We continuously increase investment in environmental protection and regularly conduct safety production education and training for employees, instilling the concepts of safety and environmental protection in every staff member.
