• Water resistant: Provides resistance to water for applications exposed to moisture.
• Oxidation resistant: Provides good resistance to oxidation during service.
• No intentional PTFE or PFAS: DuPont states that the product contains no intentionally added polytetrafluoroethylene (PTFE) or per- and polyfluoroalkyl substances (PFAS).

Product Specifications

Low-Temperature Lubrication Performance

MOLYKOTE 33 Medium is specifically formulated for applications where low-temperature performance is a primary lubrication requirement. Its silicone base provides a wide operating range and helps maintain suitable lubrication characteristics as temperatures fall to extremely low levels.

DuPont specifies a service-temperature range extending from -73°C to 180°C. The manufacturer also reports low-temperature torque testing at -73°C, making MOLYKOTE 33 Medium a suitable option for applications where minimizing resistance to movement at very low temperatures is important.

Storage and Usable Life

According to the manufacturer, MOLYKOTE 33 Medium has a usable life of 60 months from the date of production when stored in the original unopened container between 0°C and 40°C (32°F and 104°F).

Store the product in accordance with the manufacturer's current technical documentation and container labeling.

Frequently Asked Questions

What is MOLYKOTE 33 Medium grease?

MOLYKOTE 33 Medium is a silicone-based, lithium-thickened NLGI Grade 2 grease designed for light-load applications across a wide range of temperatures, including extremely low-temperature environments.

What temperature range can MOLYKOTE 33 Medium handle?

DuPont specifies a service-temperature range of -73°C to 180°C (-99°F to 356°F) for MOLYKOTE 33 Medium Extreme Low Temperature Grease.

Is MOLYKOTE 33 Medium suitable for bearings?

Yes. DuPont lists rolling element bearings and plain bearings among the applications for MOLYKOTE 33 Medium. The product is intended for light-load applications, so the specific bearing, load, speed, temperature, and lubrication requirements should be verified before use.

Is MOLYKOTE 33 Medium compatible with plastics?

DuPont states that MOLYKOTE 33 Medium is compatible with most plastics. Compatibility should nevertheless be confirmed for the specific plastic, elastomer, or other material used in the application.

What is the NLGI grade of MOLYKOTE 33 Medium?

MOLYKOTE 33 Medium is an NLGI Grade 2 grease.

What is the difference between MOLYKOTE 33 Medium and 33 Light?

MOLYKOTE 33 Medium is an NLGI Grade 2 grease, while MOLYKOTE 33 Light is an NLGI Grade 1 formulation. Both are designed for extreme low-temperature applications, but the appropriate consistency depends on the specific application and equipment requirements.

How should MOLYKOTE 33 Medium be applied?

Clean the lubrication point before application. DuPont states that the grease can be applied using a brush, spatula, or automatic lubrication device. Follow the equipment manufacturer's lubrication instructions for the appropriate quantity and application method.
