On May 15, 2026, an industrial buyer from Algeria visited ztshoil’s R&D center and manufacturing facility in Anhui, China. The visit focused on high temperature grease selection, application scenarios, and possible market cooperation in Algeria.

The customer spent the day in technical discussion with ztshoil’s international business team. The itinerary included an R&D center introduction, a factory tour, product comparison, and preliminary cooperation talks in French.
Visit at a Glance
The customer first visited ztshoil’s R&D center in Hefei, where the team introduced the company’s lubricant and grease development capabilities, export experience, and technical support process for overseas customers.

The group then moved to the production site in Susong Economic Development Zone to inspect grease manufacturing, quality control, packaging, and export preparation.
The core topic of the visit was simple: which high temperature grease is the best fit for Algerian industrial applications?
What the Algerian Buyer Needed
The buyer was looking for grease for equipment that works under high heat, heavy load, dust, moisture, and long service intervals. These conditions are common in industries such as steel, cement, construction machinery, transport, and kiln-related equipment.
For this type of use, the selection usually depends on four factors:
- operating temperature
- load-bearing performance
- water resistance
- grease retention and service life
That is why the discussion centered on a comparison between five products rather than a single product introduction.
Product Comparison: Which Grease Fits Which Application?
| Product | Base / Thickener Type | Drop Point | Working Temperature | Key Strength | Best Fit |
|---|---|---|---|---|---|
| HP-2 Blue High Temperature Grease | Refined mineral oil + composite metal soap | ≥ 260°C | −20°C to 200°C | Balanced performance and broad industrial usability | General high-temperature heavy-load equipment |
| HP-X Blue High Temperature Grease | Upgraded composite metal soap formula | ≥ 270°C | −20°C to 220°C | Higher thermal margin than HP-2 | Equipment with more frequent heat spikes |
| HEP Specific Blue High Temperature Grease | High-spec composite metal soap grease | ≥ 300°C | −20°C to 220°C | Higher drop point and stronger high-temperature reserve | Metallurgy, casting, rolling, and other severe-duty uses |
| Ultra-High Temperature Grease | Synthetic base oil + inorganic thickener + solid lubricants | No conventional drop point; structure retained up to 600°C | Suitable for extreme heat service | Designed for temperatures beyond soap-based grease limits | Kilns, furnace doors, baking chains, and similar equipment |
| Heavy Duty Vehicle Hub Grease | Multi-component complex soap grease | ≥ 280°C | −30°C to 200°C | Strong hub bearing protection under heat, speed, and load | Truck wheel hub bearings and wet service conditions |
Selection Logic
If the application is general industrial high temperature service, HP-2 is the practical starting point.
If the equipment sees higher or less stable heat exposure, HP-X offers a wider thermal buffer.
If the operating environment is more severe and the buyer needs a higher drop point, HEP is the stronger choice.
If the application exceeds the practical range of soap-thickened grease, such as kiln or furnace-adjacent equipment, Ultra-High Temperature Grease is the more suitable option.
If the main target is heavy-duty vehicle wheel hub lubrication, Heavy Duty Vehicle Hub Grease is the relevant product.

Product Details
HP-2 Blue High Temperature Grease
HP-2 is formulated with refined mineral oil and a composite metal soap thickener. It also contains extreme-pressure anti-wear additives, anti-rust additives, and antioxidants.
| Parameter | Value |
|---|---|
| Appearance | Blue uniform ointment |
| Working penetration (0.1 mm) | 220–250 |
| Drop point | ≥ 260°C |
| Operating temperature range | −20°C to 200°C |
| Water washout (38°C, 1h) | ≤ 10% |
| Steel mesh oil separation (100°C, 24h) | ≤ 3% |
| Corrosion resistance (52°C, 48h) | Qualified |
Typical applications: heavy-duty trucks, continuous casting machines, rolling mills, sintering machines, kiln cars, large motors, hot rolling mills, cement equipment, and other high-temperature heavy-load friction points.
Best use case: this is the baseline option when the buyer needs a stable industrial grease with broad compatibility.
HP-X Blue High Temperature Grease
HP-X is positioned as an upgraded version of HP-2. It keeps the same general usage range but provides a higher drop point and a wider operating margin.
| Parameter | Value |
|---|---|
| Working penetration (0.1 mm) | 220–250 |
| Drop point | ≥ 270°C |
| Operating temperature range | −20°C to 220°C |
| Water washout (38°C, 1h) | ≤ 10% |
| Leakage (104°C, 6h) | ≤ 2.5 g |
| Corrosion resistance (52°C, 48h) | Qualified |
Typical applications: the same industrial fields as HP-2, especially where temperatures rise above 200°C or thermal fluctuation is frequent.
Best use case: choose HP-X when HP-2 is close to the limit but the application does not yet require an extreme-temperature product.
HEP Specific Blue High Temperature Grease
HEP is the highest-specification product in ztshoil’s composite metal soap series. It is designed for more demanding thermal environments.
| Parameter | Value |
|---|---|
| Working penetration (0.1 mm) | 220–250 |
| Drop point | ≥ 300°C |
| Operating temperature range | −20°C to 220°C |
| Steel mesh oil separation (100°C, 24h) | ≤ 3% |
| Similar viscosity (−10°C) | ≤ 1200 Pa·s |
| Corrosion resistance (52°C, 48h) | Qualified |
Typical applications: heavy-duty trucks, metallurgy casting, steel rolling tables, printing and dyeing equipment, kiln cars, and other severe-duty applications.
Best use case: this product is the safest option when the buyer wants the strongest thermal reserve inside the soap-thickened grease category.
Ultra-High Temperature Grease
This product is different from the three blue high-temperature greases above. It uses a synthetic base oil, inorganic thickener, solid lubricants, and high-temperature anti-oxidation additives.
| Parameter | Value |
|---|---|
| Appearance | Black smooth uniform ointment |
| Working penetration (0.1 mm) | 265–295 |
| Drop point | None; structure retained up to 600°C |
| Steel mesh oil separation (100°C, 24h) | ≤ 1% |
| Corrosion resistance (52°C, 48h) | Qualified |
Typical applications: bearings and friction parts in cement, ceramics, glass, textile, and metallurgy equipment; kiln car bearings; furnace door gears; baking equipment bearings and drive chains.
Best use case: select this product when conventional soap-based grease is no longer enough for the temperature profile.
Heavy Duty Vehicle Hub Grease
This grease is designed for wheel hub bearings in large and medium-sized heavy-duty vehicles. It is intended for high temperature, high speed, heavy load, and wet service conditions.
| Parameter | Value |
|---|---|
| Working penetration (0.1 mm) | 265–295 (3#) |
| Drop point | ≥ 280°C |
| Operating temperature range | −30°C to 200°C |
| Leakage (104°C, 6h) | ≤ 2.5 g |
| Corrosion resistance (52°C, 48h) | Qualified |
Typical applications: wheel hub bearings of Steyr, Dongfeng, Jiefang, Jianghuai, Ankai, and other heavy-duty truck brands, plus other high-load bearings in special operating conditions.
Why This Product Set Matters for Algeria
For industrial buyers in Algeria, the main issue is not just high ambient temperature. The more important question is whether the grease can still hold structure, resist washout, and maintain lubrication during long service cycles in dusty, high-load environments.

That is why the product discussion moved from general high-temperature grease to a range that covers three levels of thermal demand:
- standard high-temperature industrial service
- higher thermal margin under fluctuating heat
- extreme-temperature service beyond soap-based grease limits

The buyer showed interest in introducing the relevant grease products into Algeria for industrial use and possible regional distribution. Technical follow-up will focus on final product matching, order structure, and application details.
Conclusion
The visit was less about a general factory tour and more about matching the right grease to the right working condition.
For buyers in Algeria who need high-temperature lubrication, the practical choice depends on the application:
- HP-2 for general industrial high-temperature use
- HP-X for a wider thermal margin
- HEP for severe-duty high-temperature service
- Ultra-High Temperature Grease for equipment beyond the limit of soap-based grease
- Heavy Duty Vehicle Hub Grease for transport wheel hub bearings
This structure makes the product range easier to compare and easier to specify.
