- Visitor: lubricant trading company, South Korea
- Products discussed: lithium grease, PFPE grease, GL-4 and GL-5 vehicle gear oil, L-HM anti-wear hydraulic oil
- Itinerary: production base in Susong, then the R&D centre in Hefei
- Follow-up topics: samples, Korean labels and packaging, lead times and minimum orders

| Visitor | Lubricant trading company, South Korea |
| Sites visited | Production base, Susong Economic Development Zone; R&D centre, Hefei |
| Products discussed | Lithium grease, PFPE grease, GL-4 and GL-5 vehicle gear oil, L-HM anti-wear hydraulic oil |
| Follow-up | Samples of lithium and PFPE grease; label and packaging options; lead time and minimum order for each product |

The visit started at our production base in Susong, Anhui. The visitors toured the blending lines, filling stations, quality-inspection points, the finished-goods warehouse and the packing area for export orders. They asked about batch consistency, lead times and minimum order quantities, and our sales and operations staff answered on site. The pack formats they saw included 18 L pails, 5-gallon pails and 200 L drums. Our annual capacity is 500,000 tonnes of lubricating grease and 200,000 tonnes of lubricating oil.
The second stop was the R&D centre in Hefei, home to our academician workstation and post-doctoral research station. Our chief scientist is Li Yadong, an academician of the Chinese Academy of Sciences. Engineers walked the visitors through how a formulation is developed, from base oil and additive selection to bench testing against Chinese GB standards.

The product discussion covered four lines. The figures below are the ones in our product manuals; PFPE grease data is available on request.
| Product | Manual values |
|---|---|
| Automotive multi-purpose lithium grease 2# / 3# | NLGI 2 / 3; worked penetration 265–295 / 220–250 (0.1 mm); dropping point ≥180 °C; service range −20 to 120 °C |
| PFPE (perfluoropolyether) grease | Data sheet on request |
| GL-4 and GL-5 vehicle gear oil | API service categories GL-4 (medium duty) and GL-5 (heavy duty); data sheet per viscosity grade on request |
| L-HM anti-wear hydraulic oil | ISO VG 32, 46, 68, 100, 150; typical viscosity at 40 °C 31.32 / 46.25 / 67.04 / 98.74 mm²/s (VG 32 to 100); viscosity index 95 to 105; GB 11118.1-2011 (L-HM); general grade meets the requirements of Parker Denison HF-1 and HF-2 |
Zhongtian product manuals, March 2026 edition. Hydraulic oil figures are typical values; grease penetration, dropping point and service range are the published limits. None are batch results. Ask for the current TDS before you write any figure into a purchase specification.
After the tour, the two sides discussed samples of the lithium and PFPE greases, label and packaging options for the Korean aftermarket, and lead times and minimum orders for each product. Our standard terms are a minimum order of 20 units, 3 to 7 days from stock and 10 to 20 days when made to order. Customers named in our catalog include KOBELCO, HITACHI, Conch, JAC, Dongfeng Motor and Heli. For a wider view of what the grease range covers, see our guide to grease types.
