Ester Base Oil For Aviation Engine Lubricant
Introduction:
Esters for aviation engine oil of G1820 and G1830 series are biodegradable diesters with high oxidation stability, low volatility and excellent fluidity at low temperature. They can be used alone or in combination with other synthetic materials.G2824 and G2825 series aviation engine oil esters are produced by reaction of neopentyl polyols with various saturated fatty acids, then processed by special post-treatment. They can provide the benefits such as:
high quality, highflash point, low pour point,good kinematic viscosity at low temperature, anti-coking, outstanding biodegradation and environment friendly.
Performance:
● Excellent thermal oxidation stability
● Excellent solubility of additives
● Improving the adhesion of oil products to metals
● Good wear reduction and anti-wear characteristics
● Biodegradable and no pollution
