The main performance characteristics of polyurea-based greases
Polyurea grease is a new type of grease made from urea compound thickened base oil, which has the following properties.
1. Excellent high temperature resistance
Its dropping point can reach above 270 ~ 300 ℃, polyurea-based grease is more suitable for high temperature lubrication.
2. Excellent oxidation resistance
Polyurea-based greases have significantly better oxidation resistance than commonly used greases such as lithium-based greases. Under high temperature conditions, the performance of polyurea-based greases is more stable, and changes in indicators such as penetration are small.
3． Excellent water resistance
Good quality polyurea-based grease products have a water loss of only about 1% in the water resistance test, which is much better than commonly used greases such as lithium-based greases.
4． Excellent lubrication and anti-wear properties
A thick layer of compound is formed on the friction parts where polyurea-based grease is used, which prevents direct contact between the metal on the friction surface and reduces wear. In bearing running tests conducted abroad, bearings with polyurea-based grease have a longer life.
5. Excellent acid and alkali resistance
Polyurea-based grease has excellent resistance to acids and alkalis, and can maintain a good lubrication condition in environments with high acidity and alkalinity. It is especially suitable for chemical equipment lubrication.
