Complex esters


Complex esters are polymeric structures of neopolyol esters that can reach high viscosity levels while maintaining good low-temperature properties.

Main advantages

•    Wide viscosity range, up to 10 000 mm2/s at 40°C
•    High thermal and oxidative stability
•    High film thickness and surface activity
•    Good biodegradability and low eco-toxicity, depending on the structure
•    Cost-effective


NYCO’s complex esters can be used as base-stock for the formulation of:

•    2-stroke engine oils
•    Hydraulic fluids
•    Gear oils
•    Greases
•    Metalworking fluids

Thanks to their high film thickness properties, they can also be used as a performance additive in metalworking fluids to synergistically improve EP properties.

Many of our complex esters are also suitable for environmentally-considerate lubricants such as those used in European Ecolabel compliant lubricants.  See our NYCOGREEN offer for more information.

Some NYCO complex esters have also been granted HX-1 certification, allowing their use in Food Grade Lubricants approved for incidental food contact (H1-certified). Learn more here.
