XYC DH 3-150 N 1KG is a PFPE high-temperature lubricating oil for demanding lubrication applications involving sintered metal plain bearings and plastic components. It is supplied as a clear, colorless and odorless liquid and is designed for applications requiring stable lubrication under elevated temperatures.

The DH 3 formulation is based on perfluorinated polyether PFPE oil. The supplied technical information states that the DH 3 oils were developed for lifetime lubrication under demanding conditions and contain a PFPE oil mixture with excellent thermal stability and low evaporation rate.

XYC DH 3-150 N provides a service temperature range from approximately -25°C to +200°C. This temperature range makes the 150 grade suitable for selected high-temperature lubrication applications where the operating conditions fall within the specified range.

The kinematic viscosity is approximately 150 mm²/s at 40°C and approximately 18 mm²/s at 100°C. This viscosity grade provides a higher-viscosity PFPE oil option for applications requiring stable fluid lubrication at elevated temperatures.

A primary application of the DH 3 series is the impregnation of sintered metal plain bearings. The supplied document states that DH 3 oils are used for sintered metal plain bearings subject to high temperatures where long-term lubrication is required.

XYC DH 3-150 N can also be used for plastic components and metal-plastic sliding contact surfaces. The supplied information describes these oils as clear, colorless and odorless and states that they do not form unwanted resins.

The PFPE formulation provides good compatibility with many component materials. The source states that DH 3 oils are generally regarded as neutral toward elastomers and plastics, while recommending compatibility testing before series application, particularly when perfluorinated rubber is involved.
