Plastic greases

The use of synthetic greases in systems containing plastic components requires formulations specifically designed to avoid any degradation of the polymer.Samaro, official distributor of MOLYKOTE® lubricants from DuPont, offers a range of high-performance greases that ensure reliable, durable lubrication while maintaining full plastic compatibility.
Key requirements for plastic-compatible synthetic greases
A high-quality synthetic grease for plastics must meet the following technical criteria:


Chemical compatibility with plastics (no swelling, shrinking, or loss of mechanical properties)
Prevention of stress-cracking (cracks under mechanical stress)
No oil separation over time
Noise and vibration reduction
Thermal stability and consistent behavior under shear

 
Typical applications: plastic gears and precision mechanisms
Plastic-compatible synthetic greases from the MOLYKOTE® range are particularly well-suited for:


Plastic gears in automotive applications (seat adjusters, dashboards, window regulators, etc.)
Electrical and household appliances (printers, mixers, CD/DVD drives, etc.)
Precision mechanisms and medical devices, where smooth, quiet, and reliable operation is essential

Thanks to their advanced formulation based on synthetic base oils (PAO, esters, PFPEs...) and carefully selected thickeners and additives, these greases provide consistent, low-friction lubrication with no material degradation or migration.
