BAKLUCK Polyol Ester 3009 is a relatively light ester with kinematic viscosities of 24.5 mm²/s at 40 °C and 5.0 mm²/s at 100 °C. A -58 °C pour point gives formulation teams a specific low-temperature marker, while the 266 °C flash point and viscosity index of 134 help frame its higher-temperature profile. Refrigeration-lubricant formulation trials are one screening direction; turbine and compressor-fluid studies using a light ester component are another, subject to full blend testing. Polarity, material compatibility, hydrolytic stability, additive response and the required finished-fluid standard must be established in the complete blend.
