Sinopec All Lithium Grease stands among the trusted lubricants in global industries, known for reliable performance in machinery, automotive applications, heavy equipment, and agricultural uses. The product takes its structure from a blend of mineral base oil thickened by lithium soap. These lithium soaps form by combining lithium hydroxide with fatty acids sourced from natural fats and oils, creating a thickener with a stable, fibrous network throughout the oil phase. This structure helps retain oil under pressure and withstand temperature fluctuations.
This grease delivers a semi-solid form, creamy to smooth in texture and presenting a white or pale yellow cast, a direct sign of minimal impurities. Specific gravity typically falls between 0.85 and 0.95, indicating a denser, more substantial mass compared to lighter base greases. The product resists water washout—key for automotive and machinery exposed to damp conditions. Its dropping point ranges from 180 °C to 200 °C, which allows safe use in environments with high temperature spikes. The consistency, measured by worked penetration at 25°C, often lands within 220 to 250 mm/10, slotting it into NLGI grades 2 or 3, matching general machinery lubrication.
Lubrication value comes down to more than smooth feel or color. Sinopec All Lithium Grease displays high mechanical stability. This means repeated movement and force don’t break down its fibrous matrix right away, so the grease clings to metal. It works against rust and corrosion, using additives that leave a protective film over bearing surfaces. Basic formula includes mineral oil base, lithium fatty acid soap thickener, and performance additives—these cover antioxidants, antiwear, and anticorrosion agents.
Molecular structure starts with lithium 12-hydroxystearate, a compound formed from lithium hydroxide (LiOH) and 12-hydroxystearic acid (C18H36O3). While grease is not a single molecule, lithium 12-hydroxystearate roughly approaches the formula C18H35LiO3. Blended with different hydrocarbon molecules in the base oil, the overall chemical profile includes long-chain hydrocarbons interspersed with lithium-based soap. The soap thickener absorbs and binds oil, maintaining dispersion throughout while offering resistance to thermal breakdown. This molecular makeup gives the grease its properties: tack, stability, and resistance to oxidation or breakdown.
Bulk form most often shows as a semi-solid paste, scooped by hand or pump. Grease does not crystallize like salts, nor pour like liquids, but delivers as a homogenous mass. Consumers rarely see it as flakes, pellets, powder, or liquid, and the density closely matches mineral oils, offering around 0.9 g/cm³. It packs well in drums, kegs, cartridges, and bulk containers, each form protecting against air, dust, or moisture.
Each grade meets strict industry benchmarks, including ASTM D217 for worked penetration, ASTM D2265 for dropping point, and ASTM D1743 for rust protection. Greases manufactured by Sinopec list their composition and test results on technical data sheets, and the Harmonized System (HS) code for most lithium-based lubricating greases lands at 3403.19.0000 for customs and shipping regulations. Lab reports include viscosity, consistency, oxidation stability, and load-carrying capacity, all tested in real-world or accelerated conditions.
Safety matters whenever handling lubricants, so Sinopec’s product avoids extreme chemical reactivity or volatility. The raw materials—liquid mineral oils, lithium soaps, and select additives—are engineered to keep hazardous compounds minimal. Some performance additives could rank as irritants or present potential harm if ingested or splashed in eyes, so gloves and eye protection should go hand in hand with handling, just as in oil changes or machinery servicing. The grease is not classified as hazardous per GHS standards, though disposal in line with local environmental controls is non-negotiable. Its persistence means it should never drain into watercourses or soil, as it lingers longer than oils with rapid biodegradation. Used wisely, the product offers long intervals between relubrication, cutting total chemical usage and waste.
Most of today’s lithium greases source their lithium from brine extraction or mineral deposits, many of which come from mines in China, South America, or Australia. Base oils flow from refinery streams and may be classified as paraffinic or naphthenic, selected for viscosity and purity. Additives stem from dedicated chemical plants, each batch optimized for performance in harsh, wet, high-load, or low-temperature service. Large-scale blending sites oversee quality control at every stage, with batch testing to track consistency, adherence to standards, and traceability back to origin. Raw material sourcing is under growing scrutiny given lithium’s global demand in batteries, leading to concerns about sustainability and fair resource allocation.
Every day, lithium grease plays a vital but rarely noticed role in daily life—from truck axles and industrial conveyor gears to smaller bearings in kitchen gadgets. Engineers and mechanics trust it to withstand pressure, temperature shifts, and the constant attack of corrosion. The core value stems from its chemistry, and behind that, the hard facts of raw material extraction and the worlds of people driving dump trucks or testing blends in steel drums. Out on the repair bay floor, the product makes the difference between a humming machine and a seized bearing. Safe use and smart disposal protect mechanics and the world outside the shop floor. Everyone from warehouse handlers to engineers in testing labs keeps an eye on specification sheets, making sure the product in hand matches the robustness needed for every job.
