Mobil SHC Polyrex 462
Mobil SHC Polyrex 462 is a high-performance synthetic polyurea grease developed to solve high-temperature lubrication challenges in both general industry and food processing applications. It is formulated using advanced polyurea thickener technology combined with synthetic base oils to deliver excellent thermal stability, water resistance and balanced wear protection. The grease is NSF H1 registered for incidental food contact and manufactured in ISO 22000 certified facilities, supporting use in applications requiring high product integrity.
One of the key advantages of Mobil SHC Polyrex 462 is its outstanding high-temperature capability. The synthetic formulation resists oxidation and maintains structural stability at temperatures up to approximately 170°C, helping extend relubrication intervals and maintain reliable lubrication. The grease also provides excellent load-carrying capability, helping reduce bearing wear and extend equipment life in heavily loaded applications.
Mobil SHC Polyrex 462 also offers excellent water resistance and corrosion protection. These characteristics help protect components in wet or humid environments and applications subject to frequent washdowns. The polyurea thickener helps maintain grease consistency, ensuring dependable lubrication performance under severe operating conditions.
Another important benefit is its NLGI 2 consistency with higher viscosity base oil, providing enhanced film thickness for heavily loaded bearings. Mobil SHC Polyrex 462 is recommended for extreme temperature applications such as steam heated rolls, exhaust fan bearings, felt roll bearings and oven conveyor bearings. The grease delivers reliable performance across a wide operating temperature range of approximately −20°C to 170°C.
Mobil SHC Polyrex 462 is suitable for heavy-duty plain and rolling element bearings requiring high-temperature performance, strong load protection and corrosion resistance. It is also suitable for food processing equipment and industrial applications operating under severe conditions where NSF H1 registered grease is required.
Physical characteristics include NLGI 2 consistency with a polyurea thickener and base oil viscosity of approximately 460 mm²/s at 40°C and 40 mm²/s at 100°C. Mobil SHC Polyrex 462 has a dropping point of approximately 270°C and provides excellent wear protection, strong corrosion resistance and reliable performance in high-temperature bearing applications.
