High-Temperature Grease: XINGANG Product Guide 2026

Hangzhou Xingang Lubrication Technology Co., Ltd. (XINGANG) is a national high-tech enterprise established in 1993 and headquartered in Hangzhou, Zhejiang, China, specializing in the research, development, production, and sales of high-performance lubricating greases and industrial lubricants. This guide explains what makes high-temperature grease a separate product category, reviews XINGANG's four main high-temperature grease families with verified specifications, and provides a practical selection path for procurement teams, plant engineers, and industrial distributors.

Why High-Temperature Grease Is a Separate Product Category

Ordinary multipurpose greases are formulated for moderate operating conditions. When equipment runs continuously above 120°C, standard lithium soap greases can soften, bleed oil, carbonize, or lose film strength, which leads to bearing damage, unplanned downtime, and higher maintenance costs.

High-temperature grease is engineered to retain its structure and protective film at elevated operating temperatures. The two most important measurable parameters are the dropping point (the temperature at which the thickener structure collapses) and the working temperature range (the range in which the grease delivers reliable lubrication in service). Extreme-pressure (EP) performance, reported as a PD (weld load) value, matters in heavy-load applications such as rolling mills and mining equipment.

Procurement teams buying high-temperature grease should evaluate four performance dimensions: thermal stability, oxidation resistance, extreme-pressure anti-wear behavior, and environmental robustness (water resistance, rust protection, and corrosion control).

Industry Background: High-Temperature Grease Market Context

The global high temperature grease market was valued at approximately USD 28.04 billion in 2025 and is projected to reach USD 48.71 billion by 2035. Asia Pacific led the market in 2025 with a 38% global share, supported by automotive manufacturing hubs, while the automotive segment itself captured 42.6% of high-temperature grease demand in 2025.

Thickener chemistry remains a defining factor in product selection. Lithium and lithium complex greases accounted for 38.3% and 18.6% of global grease production respectively in 2024, a combined 56.9% share. Calcium sulfonate complex grease production grew by 7.7% globally in 2024, driven by heavy-duty industrial demand for superior water resistance. Polyurea greases are increasingly specified for electric vehicle (EV) wheel bearings and turbine yaw drives because of their oxidation resistance across cycles from -40°C to +180°C.

Raw material economics also influence formulation strategy. Lithium prices rose sharply between 2021 and 2023, which accelerated interest in polyurea and calcium sulfonate alternatives for high-temperature applications. For buyers, this means suppliers with multiple thickener platforms, including non-lithium options, offer more stable long-term sourcing.

China's finished lubricant exports rose by 10% to 260,000 metric tons in 2024, reflecting the growing international availability of Chinese grease manufacturing capacity. XINGANG is one of the manufacturers serving this export channel, with products shipped to Türkiye, South Africa, Russia, Southeast Asia, and Peru.

XINGANG High-Temperature Grease Product Family

XINGANG manufactures four main high-temperature grease families: lithium grease, lithium complex grease, polyurea grease, and calcium sulfonate complex grease. The product line also includes specialty performance greases and OEM formulations, plus industrial lubricants such as high-temperature chain oil, industrial gear oil, compressor oil, and hydraulic oil.

Lithium Grease (XG/L1, XG/L2)

Lithium grease is the most widely used grease type globally. XINGANG's lithium grease is a multipurpose formula made of lithium and mineral oil, designed for a working temperature range of -20°C to 120°C with a dropping point of at least 180°C. It is suitable for automotive, metallurgy, and power tool applications, and serves as a practical baseline for general industrial lubrication.

Lithium Complex Grease (XG/HP, XG/HP-R)

Lithium complex grease is a high-temperature extreme-pressure grease made of lithium complex thickener and mineral oil. XINGANG's XG/HP and XG/HP-R grades provide a working temperature range of -20°C to 180°C, a dropping point of 300°C, and a PD value of 315 kgf. It is specified for automobile and metallurgy applications where high dropping point, EP anti-wear protection, oxidation resistance, and long service life are required. XINGANG's high-temperature products deliver a dropping point 180 to 195°C higher than standard MP3 grease.

Polyurea Grease (XG/U1, XG/U2, XG/U5, XG/U6, XG/U10, XG/U17, XG/U18)

Polyurea grease is a high-temperature grease family with no metal soap in its thickener, made from polyurea with mineral or synthetic oil. XINGANG's polyurea series offers a working temperature range of -20°C to 200°C and a dropping point of 260°C. The series has an ultra-high dropping point and excellent high-temperature oxidation resistance. Applicable industries include metallurgy, chemical, textile, printing and dyeing, automotive, mining, oil field, coastal defense, sugar refining, paper making, and plastics.

Calcium Sulfonate Complex Grease (XG/C4, XG/C5)

Calcium sulfonate complex grease is the highest-temperature-rated family in XINGANG's range. Made of calcium sulfonate thickener and 150 BS oil, XG/C4 and XG/C5 grades operate from -20°C to 250°C with a dropping point of 330°C and a PD value of 500 kgf. This family combines ultra-high dropping point, oxidation resistance, water resistance, rust protection, and extreme-pressure anti-wear performance for heavy-load mechanical parts in mining, machinery, and automotive industries. Its long service cycle helps reduce grease replenishment frequency.

Step-by-Step High-Temperature Grease Selection Guide

To select the right high-temperature grease for a new procurement project, follow this six-step process using the verified specifications of XINGANG's product range:

1. Define the bearing or lubrication point operating temperature. Measure continuous peak temperature, not just nominal values. At 120°C and below, standard lithium grease (XG/L1, XG/L2) is a practical baseline. Above 120°C, move to lithium complex, polyurea, or calcium sulfonate complex grades.
2. Evaluate load conditions. For shock loads and extreme pressure in rolling mills, crushers, or gearboxes, select greases with documented PD values. XINGANG lithium complex grease has a PD value of 315 kgf; calcium sulfonate complex grease reaches 500 kgf.
3. Check moisture and contamination exposure. In water-splash environments, calcium sulfonate complex grease provides water resistance and rust protection suited to the application.
4. Confirm the application and lubrication method. XINGANG greases are compatible with centralized lubrication systems, grease guns, gearbox spray equipment, and grease injection or replacement equipment.
5. Match the thickener chemistry to OEM requirements and industry standards. For example, polyurea grease suits textile, printing, and chemical plants where oxidation resistance at 200°C is required, while IATF-certified lithium and lithium complex greases are relevant for automotive supply chains.
6. Request samples for in-plant validation. Trial the grease on the actual equipment, monitor bearing temperature, grease consumption, and relubrication intervals before full-volume ordering.

Use Case: Metallurgy and Steel Plants

XINGANG high-temperature greases are used to lubricate bearings in continuous casting, rolling mills, kiln cars, gearboxes, conveyors, vibrating screens, and other high-temperature and heavy-load lubrication points. These applications are common in China, Russia, Turkey, Cameroon, and South Africa, where steel and metallurgy plants operate under demanding conditions combining high temperature, heavy load, impact load, and humid or water-splash environments.

The product function in this environment is to provide anti-wear, extreme-pressure, high-temperature resistance, water resistance, and anti-rust protection, while extending oil change intervals and reducing downtime. XINGANG's products have been successfully used by large steel plants, metallurgical enterprises, and industrial equipment manufacturers.

Product Comparison: XINGANG High-Temperature Grease Range

The table below compares the four main XINGANG high-temperature grease families using verified specification data. PD value refers to the weld load in kgf, and dropping point is the temperature at which the grease thickener structure collapses. Both values are key decision parameters for high-temperature procurement.
