Hebei Jimaijimai Polyurethane Synthetic Materials Co., Ltd., under its Haoyou Adhesives brand, has been deeply engaged in the polyurethane synthetic materials industry for more than 20 years. With sound business strategies, continuous technological accumulation, and stable product quality, the Company has steadily expanded its market coverage and gradually increased its business scale. As industry technologies continue to evolve and market demand for cooperation grows, the original production site could no longer meet the Company's needs for large-scale and standardized development. To keep pace with industry development and business expansion, the Company independently completed industrial upgrading and the construction and expansion of its plant, investing tens of millions of yuan to improve supporting production hardware and software facilities, establish a modern standardized production facility, and comprehensively enhance production capacity and standardized operational capabilities. The Company is now located on the west side of the intersection of Ping'an Road and Wusong East Street, Gexianzhuang Town, Qinghe County, Xingtai City, Hebei Province. Its advantageous location and convenient transportation provide favorable conditions for product warehousing, logistics shipments, and on-site customer engagement.

       To strengthen product quality and R&D capabilities, the Company continuously upgrades its production system, successively introducing professional production equipment, precision testing instruments, and supporting laboratory R&D equipment to establish a complete operating system integrating product R&D, large-scale production, and quality testing. The Company focuses on the R&D and production of polyurethane synthetic materials and auxiliary materials for filter applications. Its core products include filter PU adhesive, iron cover adhesive, elastomer aluminum, integral skin foam, release agents, DMF, and other supporting auxiliary material series. These products are widely suitable for various application scenarios, including automotive filters, construction machinery engine filters, heavy-duty truck filters, and filter plastics, meeting the manufacturing requirements of various types of filters.

       Relying on its comprehensive R&D and production system and stable, reliable product performance, the Company actively participates in industry standardization and completes the filing of relevant industry standards in accordance with regulations, controlling product quality through standardized production processes. With stable product performance, a diverse product range, and attentive supporting services, the Company's products have gained wide recognition from numerous filter manufacturers. The Company has long provided supporting products to the supply chains of major vehicle manufacturers and has developed deep expertise in commercial vehicle and construction machinery filter applications, earning a strong industry reputation and stable customer base.

       The Company has established professional and experienced domestic and overseas sales service teams and technical R&D teams. Having long worked on the front lines of the industry, the teams continuously absorb cutting-edge production technologies and R&D concepts through ongoing industry research, technical exchanges, and field visits. They continuously optimize product formulations and improve production processes, focusing on the development of new polyurethane series products that are environmentally friendly and offer stable performance, while continuously enhancing product suitability and practicality in line with the industry's trends toward green development and refined production.

       Since its establishment, the Company has consistently adhered to the business philosophy of “integrity in business, quality first, and customers first,” upholding professional, innovative, and pragmatic development principles.
