科慕Chemours Krytox GPL217

Krytox GPL 217重型润滑脂用于高负载或低速。EP润滑脂在边界和混合摩擦条件下具有较高的承载能力和良好的润滑特性。除了Krytox GPL 217重型润滑脂中的EP添加剂外，由于在负载下形成的粘度及其独特的摩擦化学性质，Krytox油本身也能提供足够的EP保护。

Krytox GPL 217 Grease | Extreme Pressure General-Purpose Lubricants

Molybdenum Disulfide Additive, 100% Nonflammable, Chemically Inert

Krytox GPL 217 heavy-duty grease is used for high loading or slow speeds. EP greases have high load-carrying capability and good lubrication characteristics under boundary and mixed friction conditions. In addition to the EP additive in Krytox GPL 217 heavy-duty grease, Krytox oil provides adequate EP protection as an oil by itself, due to the viscosity build under load and its unique tribochemistry.

A common test for analyzing EP performance is the Timken EP method, ASTM D2509. The test is performed by applying pressure between a rotating steel cup and a steel block and simulates line contact conditions. Two conditions are observed; the OK Load is the highest load at which no seizing or welding occurs, and it also reflects the load-carrying capability of the lubricant. The Score Load is the lowest load at which seizing or welding is observed. The scar width, which is the average scar width at the load corresponding to the OK load valve, is also recorded.
