Just now and types of lubrication products

At present, we have successfully developed and put into scalable production more than ten types of synthetic esters, including PMA pour‑point depressants and viscosity modifiers, neopentyl polyol esters, natural fatty acid esters, and specialty synthetic esters for transformers. In addition, we can tailor finished products for specific applications, such as environmentally friendly polyol ester–based refrigeration oils, synthetic compressor oils, aviation lubricants, eco‑friendly transformer oils, and synthetic‑ester metalworking fluids.

Poly(methyl methacrylate) series 
Pour point depressant 
Model: G826P/G886P 
Product Applications: 
G826P: An advanced product that delivers outstanding low-temperature performance across a wide range of lubricants, particularly well-suited for catalytic dewaxing base oils and high‑ethylene‑content OCP index improvers. 
G886P: Primarily suitable for pour-point depression of low-viscosity base oils.

Poly(methyl methacrylate) series

Viscosity modifier 
Model: G6100V/G6300V/G6500V 
Product Applications: 
G6100V: This product is a novel polymer that exhibits outstanding thickening, anti‑gelling, and pour‑point‑lowering performance. 
G6300V: This product is a viscosity index improver specially formulated for hydraulic oils, offering exceptional shear stability. 
G6500V: Primarily suitable for vehicle gear oils meeting the new standards, it is specially formulated for wide-range vehicle gear oils as well as internal‑combustion engine oils, transmission fluids, CVTFs, and automatic transmission fluids (ATF). This viscosity index improver features a uniquely designed high shear stability, dissolves readily in all mineral and synthetic base oils, and exhibits excellent compatibility with other conventional lubricant additives.

Ester for biodegradable flame‑retardant hydraulic fluid 
Model: G-HFDU32/G-HFDU46/G-HFDU68 
Product Applications: The ester-based hydraulic fluid series is produced by reacting neopentyl polyol with long-chain unsaturated fatty acids or dicarboxylic acids, followed by a specialized refining process. It is particularly well suited as a base oil for fire‑resistant or biodegradable hydraulic fluids.

Ester base oils for internal combustion engine oils and industrial oils: polyol esters 
Model: G2820/G2823/G2835 
Product Applications: 
The ester-based base oils for internal combustion engines are produced by reacting neopentyl polyols with saturated fatty acids under specific, proprietary process conditions, followed by a specialized post‑treatment refining process. 
It is particularly suitable as a base stock for engine oils in viscosity grades such as 0W‑16, 0W‑20, 0W‑30, 0W‑40, and 0W‑50. It can be blended into PAO, GTL oils, and Group III hydrogen‑processed base stocks.

Ester-based base oil for aircraft engine oils: diesters 
Model: G1820 / G1830 
Product Applications: 
Esters for G1820 and G1830 series aircraft engine oils are biodegradable diesters that exhibit high oxidation stability, low volatility, and excellent low‑temperature fluidity; they can be used alone or blended with other synthetic base stocks.

Ester base oils for high-temperature chains: aromatic esters, polyol esters. 
Aromatic esters: GTM68, GTM150, GTM320 
Polyol esters: G28150, G28220, G28320, G28800 
Product Applications: 
Insufficient performance of chain oil can lead to machine downtime, increased maintenance frequency, reduced energy efficiency, poor oil–water separation, and a tendency to emulsify—potentially even causing chain deformation and breakage. High‑quality, high‑performance synthetic esters offer advantages such as appropriate lubrication for chains and ratchets, excellent thermal and oxidative stability, and superior adhesion.

High-viscosity polyalphaolefin containing ester groups, polyester 
Model numbers: GP15, GP25, GP35, GP40, GP50 
Product Applications: 
Ester-based PAO, as a base oil, exhibits numerous unique properties and demonstrates excellent solvency for additives. It can significantly reduce friction, minimize wear, inhibit foam formation, and control the generation of oil‑related deposits. Over a broader temperature range, ester‑based PAO is capable of forming a high‑strength lubricating film on a wider variety of material surfaces, providing extended lubrication duration and delivering superior lubrication performance, thereby prolonging equipment service life.

Ester for transformer oil, polyol ester 
Model: G2828 
Product Applications: 
This polyol ester is synthesized under specific conditions from a blend of saturated fatty acids and polyols. It exhibits excellent lubricity, a low coefficient of thermal expansion, a high dielectric breakdown voltage, outstanding flame retardancy, exceptional thermal‑oxidative stability, and extremely low moisture content. Consequently, it is widely suitable for power transformers up to 238 kW, traction transformers, pole‑mounted transformers, and transformers equipped with tap changers.

OCP thickener

Model: GT615 
Product Applications: Viscosity index improvers are key additives used in the formulation of multigrade internal‑combustion engine oils, hydraulic fluids, and gear oils. Adding a viscosity index improver to lubricants yields multigrade oils that exhibit excellent low‑temperature flow properties while maintaining appropriate viscosity at elevated temperatures, thereby enhancing lubricant performance, elevating product grade, extending service life, and enabling year‑round use.

Polyol ester complex 
Model: GD2000 
Product Applications: 
GD2000 is a high-viscosity composite ester with excellent hydrolytic stability and shear stability. It serves as an efficient, easy-to-use viscosity‑increasing additive for both mineral and synthetic oils, and is recommended for thickening applications across various lubrication sectors. It also functions as a foundational ingredient for enhancing lubrication performance.

Special base oil for environmentally friendly refrigeration compressor oils  
Model: RL22\32\46\68\74\100\120\150\170\220\320 
Product Applications: 
The ester base oil specially formulated for refrigeration compressor oils is produced by reacting neopentyl polyol with saturated straight‑ and branched‑chain fatty acids, followed by molecular distillation for purification. Refrigeration compressor oils blended with this proprietary ester have been successfully deployed in OEM refrigeration compressors. They exhibit excellent miscibility and compatibility with next‑generation environmentally friendly refrigerants. Its unique structural design imparts outstanding hydrolytic stability. In certain formulations, GD2000 composite ester can serve as an additive to enhance sulfur‑phosphorus extreme‑pressure agents, offering a viable alternative to chlorinated paraffins (though some formulations may require careful consideration of additive sensitivity and base‑oil miscibility). Moreover, it delivers superior thickening performance, enabling attainment of equivalent viscosity at lower addition levels.
