Over the past two decades, high-end door hinges—typically made of premium stainless steel or brass—have widely adopted fully synthetic damping grease, originally used for protecting optical and automotive components, as their core lubrication material. The grease is injected into the hinge pivot before leaving the factory, offering significant advantages:

• Excellent adhesion: Minimizes grease loss.

• Superior lubrication and corrosion protection: Extends the service life of the hinge.

• Long-lasting noise reduction and damping: Ensures smooth, quiet opening and closing with an appropriate resistance for tactile feedback.

Important note: Temperature effect on viscosity

The viscosity of damping grease varies with temperature: it decreases at high temperatures and increases at low temperatures. Therefore, when selecting damping grease:

• Always choose viscosity according to the actual operating temperature range.

• For high-temperature environments requiring stable viscosity, select products with excellent high-temperature performance and a high viscosity index.
