In China’s petrochemical sector, the shift from large-scale commodity production toward high-performance specialty materials demands leaders who combine deep operational experience with strategic foresight. Lin Qingfu, General Manager of Liaoning Dingjide Petrochemical Technology Co., Ltd., is one such executive.
Lin built his career at the heart of China’s ethylene industry. He began at PetroChina’s Dushanzi Petrochemical, rising to ethylene workshop director, deputy manager of the chemical engineering department, and ethylene plant director. He later moved to Zhejiang Petrochemical (ZPC), one of the world’s largest integrated refining and chemical complexes, where he served as Vice President and General Manager of the Ethylene Chemical Business Unit, and subsequently as Vice President of Rongsheng Holding Group. His track record spans plant operations, mega-project construction, commissioning, and industrialization of ethylene and polyolefin facilities—experience that remains relatively scarce in China’s private specialty-chemicals sector.
In 2023 Lin joined Liaoning Dingjide Petrochemical Technology Co., Ltd., a wholly owned subsidiary of the Shanghai-listed Liaoning Dingjide Petrochemical Co., Ltd. (stock code 603255). The company, founded in 2004 in Yingkou, Liaoning, with registered capital of RMB 133.46 million, had established itself as a national high-tech enterprise and a primary domestic supplier of propylene and ethylene polymerization catalysts, electron donors, antioxidants, acid scavengers, antistatic agents, and blending additives. Its customers include CNPC, Sinopec, CNOOC, China Shenhua, China Coal, and ChemChina; products are also exported. Subsidiaries include Yingkou Zhonghe Additive Co., Ltd. and a joint venture in Xinjiang. What the company lacked was large-scale downstream polyolefin project execution capability. Lin’s arrival, reinforced by an equity incentive plan that named him among core technical talent, helped close that gap.
Under his leadership, Dingjide has moved decisively into high-end materials. In 2023 the company signed an investment agreement for a roughly RMB 10 billion high-end new materials project on Dalian’s Changxing Island. The first phase centers on a 200,000-tonne-per-year POE (polyolefin elastomer) unit together with ethane-to-α-olefin facilities. Construction of the POE line began in 2024; mechanical completion was achieved in July 2025 after a 14-month campaign, and the main unit started up successfully in September 2025. The plant has already produced eight commercial grades, primarily for photovoltaic encapsulation films and compounding applications, and currently operates at approximately 10,000 tonnes per month. Once fully completed, the project is expected to deliver annual output value of around RMB 11.8 billion and to produce 200,000 tonnes of POE, 151,300 tonnes of 1-octene, 33,700 tonnes of 1-hexene, and additional specialty streams. POE, a thermoplastic elastomer made by copolymerizing ethylene with octene or butene, combines plastic processability with rubber-like elasticity and is strategically important for China’s solar, automotive lightweighting, and high-end foam markets.
Lin has simultaneously driven operational and managerial modernization. At the Changxing Island site, a 5,000-square-metre packaging warehouse runs with near-full automation: from pellet formation to palletized stacking, only a small number of staff handle exceptions. Intelligent warehousing, automated logistics, RFID tracking, and real-time data feeds via API into the ERP system have eliminated most manual recording. Finance and tax processes have followed the same path. Automated document recognition, tax separation, and voucher generation have raised accounting efficiency by more than 80 percent, cut monthly reporting from roughly three days to four hours, and reduced error rates from about 5 percent to below 0.5 percent. Tax filings that once required two working days are now completed in under an hour with near-perfect accuracy. The company is expanding a Financial Business Partner model in which finance professionals work on the production floor, monitor material and energy costs in real time, and feed actionable insights into planning and pricing—aiming for monthly cost savings exceeding RMB 1 million in targeted areas.
R&D intensity continues to rise. Lin has indicated that overall research spending will increase by more than 50 percent in 2026. Dingjide operates a provincial enterprise technology center and a CNAS-accredited laboratory, holds multiple patents and ISO 9001/14001/18001 certifications, and has been recognized as a provincial “specialized, refined, distinctive and innovative” (SRDI) “little giant” and gazelle enterprise. The company has completed dozens of technology transformations and maintains rigorous R&D accounting practices to capture available policy incentives while managing compliance risk.
Looking forward, Lin’s mandate is to integrate Dingjide’s established strengths in catalysts and additives with large-project execution capability and to expand the product portfolio into higher-value polyolefin materials. With capital-market support, continued automation, strengthened talent pipelines that blend catalyst expertise with ethylene-complex experience, and rising R&D investment, the company aims to deepen its technological and market position and to supply customized, high-quality solutions to the polyolefin industry both in China and internationally.
In an industry where scale, technology, and disciplined execution must align, Lin Qingfu brings plant-floor credibility, mega-project leadership, and a practical focus on continuous improvement. His work at Dingjide is helping translate decades of ethylene and polyolefin know-how into the next generation of materials that support China’s energy transition and advanced manufacturing goals.
