Complex esters are polymeric structures of neopolyol esters that can reach high viscosity levels while maintaining good low-temperature properties.
- 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
NYCO’s complex esters can be used as base-stock for the formulation of:
- 2-stroke engine oils
- Hydraulic fluids
- Gear oils
- 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.
