Shandong Qilong Chemical Co., Ltd. (hereinafter referred to as "Qilong Chemical") is a state-controlled enterprise. Formerly an affiliate of Sinopec Qilu Petrochemical, the company was established in 1985 and has accumulated nearly four decades of industrial expertise. It underwent corporate restructuring in 2005 and completed mixed-ownership reform in 2022, with Zibo Chengfa Industrial Investment Group becoming the controlling shareholder. Today, Qilong Chemical has grown into a leading enterprise and comprehensive solution provider in China's petroleum resin sector.

    The company is deeply engaged in the deep processing of ethylene cracking by-products, focusing on the high-value comprehensive utilization of cracked C5, C9 fractions, and ethylene tar. With its dual-base layout comprising the Zibo headquarters and Fushun Qilong Chemical, the company covers a total area of over 900 mu (approximately 60 hectares), possesses an annual raw material processing capacity of 600,000 tons, and operates 13 production units. Leveraging its two major feedstock sources—Sinopec Qilu Petrochemical and PetroChina Fushun Petrochemical—the company ensures direct pipeline supply and regional synergies, establishing a complete industrial chain spanning from feedstock separation to resin production.

    Qilong Chemical's flagship products encompass more than 30 varieties, including C9 petroleum resin, C5/C9 copolymer petroleum resin series, dicyclopentadiene (DCPD), methylcyclopentadiene dimer (MCPD), and high-efficiency water-reducer grade naphthalene. Among these, the company's C9 petroleum resin production capacity accounts for 25.55% of China's total domestic output, ranking first in the industry; its C5/C9 copolymer resin holds a 31.6% market share, demonstrating dominant influence in the niche segment; and its C9 cold-polymer petroleum resin capacity consistently ranks among the top in the industry. The production capacity, output, and market share of its core products all occupy leading positions nationwide.

    The company has taken the lead in drafting the national standard for petroleum resin (GB/T 24138-2022), as well as multiple industry standards including Dicyclopentadiene for Industrial Use and Methylcyclopentadiene Dimer for Industrial Use, thereby commanding technical authority within the sector. It has established high-level R&D platforms such as the "Provincial Petroleum Resin Engineering Research Center" and the "Provincial Enterprise Technology Center," and maintains long-term, stable industry-university-research partnerships with renowned domestic universities and research institutes. With 43 authorized patents accumulated to date, Qilong Chemical continues to drive product iteration and industrial upgrading through independent R&D.

    The company has successively obtained four major international system certifications—ISO 9001 Quality Management, ISO 14001 Environmental Management, ISO 45001 Occupational Health and Safety Management, and ISO 50001 Energy Management—and its products meet stringent international market access requirements including EU REACH and RoHS directives.
