In May 2026, a South Korean lubricant trading company traveled to Anhui Province, China, for an on-site evaluation of Zhongtian Petrochemical‘s research and development capabilities and manufacturing infrastructure. The delegation’s focus was clear: four product categories — lithium-based grease, perfluoropolyether (PFPE) grease, industrial gear oil, and anti-wear hydraulic oil — and a goal of introducing the Zhongtian brand to the South Korean distribution network. After a full day covering the production base and the R&D center, the visitor confirmed confidence in Zhongtian’s technical depth and product breadth, and signaled intent to move toward a formal distribution partnership.

Factory Visit: Scale, Quality Control, and Supply Consistency
The Korean delegation began at Zhongtian’s production base in Susong, touring automated blending lines, filling stations, quality-inspection checkpoints, and the finished-goods warehouse. The visit provided a direct view of the operational discipline behind Zhongtian’s 500,000-ton annual output claim.
Particular attention fell on the packaging and outbound logistics section, where staff demonstrated how orders are prepared for international shipment. The delegation raised questions about batch consistency, lead times, and minimum order quantities — all of which were addressed on-site by the sales and operations team.
Packaging formats inspected included standard 18 L pails, 5-gallon drums, 200 L barrels, and cartridge sizes (320 g – 15 kg) for greases — the full range that matches South Korean industrial and automotive aftermarket channel requirements.
R&D Center Tour: The Technical Foundation Behind Every Product
The second stage of the visit was spent at Zhongtian’s Hefei Research and Development Center — a facility housing advanced analysis instruments, formulation workstations, and simulation test rigs, and home to both an Academician Workstation and a Post-Doctoral Research Station.
R&D engineers walked the delegation through Zhongtian’s product development cycle: from base-oil selection and additive compounding, through bench testing for wear, oxidation, and low-temperature flowability, to final certification against Chinese GB standards, API classifications, and OEM approvals. The center is equipped with internationally advanced testing equipment, and formulation work is led by a research team under Chinese Academy of Sciences academicians as chief scientists.
For the Korean visitor — who noted that many Chinese lubricant suppliers operate purely as trading companies or blending shops — seeing a genuine research infrastructure was a decisive moment. The verified R&D capability substantially raised their confidence in recommending the Zhongtian brand to end-customers in South Korea.
Products in Focus: What the Korean Visitor Came to Evaluate
Technical discussion centered on four product lines that closely match high-performance segments of the South Korean industrial lubricant market. Below is a summary of each product category, the specifications shared with the delegation, and the specific applications discussed.
1. Multi-Purpose Lithium Grease — Automotive & Industrial Applications
Zhongtian’s lithium-based grease family is the cornerstone of its export grease portfolio. The automotive multi-purpose lithium grease (Grade 2# / 3#) is made from highly refined mineral base oil thickened with hydroxy fatty acid lithium soap, with extreme-pressure anti-wear, anti-rust, and anti-oxidation additives added through a special process.
Applications: Rolling bearings, sliding bearings, automobile hubs, chassis components, motors, water pumps, and general friction parts across an operating temperature range of –20°C to 120°C.

2. Perfluoropolyether (PFPE) Grease — Specialty High-Performance Lubrication
The PFPE grease attracted particularly strong interest from the Korean visitor. Perfluoropolyether lubricants represent the premium end of the specialty grease market, valued for their exceptional thermal stability, chemical inertness, non-flammability, and ultra-low vapor pressure — properties that no conventional mineral or synthetic grease can match.
Zhongtian’s PFPE grease is manufactured using a high-performance perfluoropolyether synthetic base, compounded with inorganic thickener, refined with low-friction lubricating solids, and enhanced with extreme-pressure and anti-wear additives. It is completely insoluble in most organic solvents and non-reactive in the presence of concentrated oxygen and chlorine.
Applications: Linear slides and guides, gearboxes, screws and threaded fasteners, anti-friction and plain bearings, valves, and any lubrication duty requiring excellent seal compatibility and component protection at temperature extremes.
