Synthetic Base Oil-Polyester for Gear Oils

Introduction As a synthetic ester base oil, polyester combines the advantages of synthetic esters and Poly α Olefin (PAO) and performs well in lubrication performance. Under extreme working conditions, this material can effectively improve the oil film strength and load-bearing capacity when used with anti-wear extreme pressure additives due to its outstanding HTHS stability.  This unique comprehensive performance makes it an important basic component of modern internal combustion engine oil and industrial gear oil formulations.  Specifications Item KV40℃ mm²/s KV100℃ mm²/s VI Pour Point℃ Flash Point℃ Acid No.    mgKOH/g Evaporation Loss C115 115 16.5 155 -49 259 0.05 1 C135 350 36.7 152 -39 273 0.05 1.5 C460 510 50 158 -35 280 0.05 1.5 C680 670 58 150 -29 280 0.05 1.7 C1500 1450 115 175 -26 250 0.05 2 C4600 5100 285 190 -14 250 0.05 2 C15000 15000 1000 280 -15 257 0.18 2 C17000 17000 1215 300 -15 257 0.18 2 C20000 20000 1415 308 -13 257 0.18 2 C25000 25000 166…
