what is ester based engine oil
Keywords:
Saturated Complex / Polyolesters
Product Introduction Saturated Polyolesters used independently or blended with other synthetic materials, and are also compatible with PAO and high-quality mineral oils. These esters are suitable for applications such as ultra-low-temperature internal combustion engine oils, aviation gas turbine oils, and environmentally friendly refrigeration compressor oils, compatible with refrigerants R-22, R-32, R-134a, R-507, R-407C, and R-410A. They can also serve as base oils for various fully synthetic or semi-synthetic lubricants. Additionally, they are used in high-low temperature greases for demanding conditions and in the food processing industry.
