Puyang Ruisen New Materials Co., Ltd. was established in March 2021 as a new joint-stock company located within the Puyang Chemical Industry Cluster Zone. Occupying 310 mu (approximately 20.7 hectares) of land with a registered capital of RMB 100 million, the company currently operates two production facilities: one with an annual capacity of 20,000 tons of modified C5 petroleum resin and another with an annual capacity of 20,000 tons of dimethyl sulfoxide (DMSO). Leveraging advanced technology and stable suppliers, its products are widely sold across multiple domestic and international sectors.

In March 2022, the company initiated Phase I construction of its modified C5 petroleum resin project. Following 18 months of engineering and equipment installation, trial production commenced at the end of October 2023. This phase primarily involved constructing office facilities, a 20,000-ton-per-year modified C5 petroleum resin production unit, and supporting utility systems. The primary product, modified C5 petroleum resin, is manufactured using advanced technology developed over more than 20 years of research. It belongs to the high-end petroleum resin category, featuring excellent initial tack, a very narrow molecular weight distribution, and outstanding compatibility with elastomers such as EVA, natural rubber, styrene-butadiene rubber (SBR), butyl rubber, polyethylene rubber (PE), and styrene block copolymers (e.g., SIS, SBS). Upstream suppliers include major refining and chemical enterprises such as Sinopec Tianjin Petrochemical, Sinopec INEOS, Sinopec Central China Branch, Yulong Petrochemical, and Yantai Wanhua, ensuring stable and reliable raw material quality and supply volume. The produced C5 petroleum resin is exported to over 20 countries and regions including the United States, Japan, South Korea, the United Kingdom, the European Union, Russia, Australia, Southeast Asia, and Taiwan, China. It is widely used in the production of adhesives, sealants, coatings, and inks. Additionally, it serves as a tackifier, thickener, and performance enhancer in road asphalt modification, rubber product modification, plastic processing, and the papermaking industry. Our customer base encompasses adhesive and sealant manufacturers, coatings and ink producers, asphalt modification and road marking paint processors. We also supply raw materials to rubber product factories, plastic manufacturers, and paper additive suppliers, serving key players across China's chemical, building materials, and light industrial sectors.

In September 2024, the company invested approximately RMB 110 million to initiate a new project for producing 20,000 tons of dimethyl sulfoxide annually, with trial production operations scheduled to commence in October 2025. This project utilizes carbon disulfide and methanol as base materials, synthesizing dimethyl sulfide through the oxidation of methyl mercaptan. The chemical park hosting the project and its surrounding areas are home to multiple carbon disulfide producers, ensuring ample capacity, convenient transportation, and competitive pricing. Methanol, as a fundamental chemical feedstock, benefits from a mature supply network, guaranteeing stable raw material availability for production. As a highly polar, high-boiling-point “universal solvent,” its applications span multiple sectors: In pharmaceuticals, it serves as a drug solvent, carrier, and organic synthesis intermediate, particularly suited for producing quinolone antibiotics like norfloxacin and ofloxacin; In the chemical industry, it serves as an organic synthesis solvent, an aromatic extraction agent, and a spinning solvent for acrylic fiber polymerization (carbon fiber). It is also utilized in pesticide adjuvants, electronic component cleaning, and coating leveling improvement applications. Primary clients include pharmaceutical API and formulation manufacturers (especially fluorinated drug producers), pesticide manufacturers, carbon fiber textile mills, electronic component processors, and coating producers. Some products reach overseas markets through import/export channels. Demand for dimethyl sulfoxide (DMSO) is growing annually. The project employs domestically leading technology and equipment, meeting product requirements in both advancement and reliability. The company possesses a large pool of technical experts and skilled workers, and the project's technical conditions are mature and reliable, fully ensuring operational stability.

The company operates under a general manager responsibility system, establishing a comprehensive management structure comprising eight departments: Office, Finance Department, Supply and Marketing Department, Technology Center, Production Department, Equipment Department, Warehousing Department, and Safety and Environmental Protection Department. Key leadership positions include Chief Engineer, Vice President of Production, Vice President of Equipment, Vice President of Sales, and Safety Director. With over 190 employees, the company boasts more than 80 mid-to-senior level technical professionals, and over 90% of staff hold college or technical school degrees. With a highly qualified workforce, robust technical capabilities, advanced production processes, comprehensive testing methods, standardized management practices, and promising market prospects, the company places significant emphasis on technological R&D. It currently employs over 30 R&D personnel and holds a cumulative total of 2 authorized invention patents, 2 software copyrights, and 8 utility model patents. The company's patented technologies—including invention patents and utility models—are either applied in product manufacturing processes or directly converted into scientific achievements, demonstrating a high degree of integration between intellectual property and core business operations. Leveraging its outstanding innovation capabilities, the company was honored as an “Innovative Small and Medium-sized Enterprise” by the Henan Provincial Department of Industry and Information Technology in December 2024. On October 11, 2025, it was jointly recognized as a “High-Tech Enterprise” by three provincial departments including the Henan Provincial Department of Finance, while also receiving certification as an “Engineering Technology Research Center” from the Puyang Municipal Science and Technology Bureau. By late October, the company successfully passed the evaluation for “Municipal-Level Enterprise Technology Center” by the Puyang Development and Reform Commission, highlighting its significant advantages in technological innovation and industry recognition.
