Providing Precision Lubricants and Lubrication Solutions


Silicone Grease: RPL-PRG

The RPL-PRG silicone food grade grease is manufactured from a 100% silicone base fluid combined with an inorganic gel thickener which provides for good thermal stability over a wide temperature range and in different operating conditions. It has low vapor pressure and superior oxidation properties.

Unlike conventional petroleum lubricants, the RPL-PRG does not dissolve or react in the presence of many active processing materials because of its special inert properties. It is resistant to a broad range of chemicals including most hydrocarbon-based solvents, methanol, ethanol, glycol, glycerin, aqueous solutions of inorganic salts, acids and alkalis, vegetable and mineral oils, fuels, organic compounds and common gases.

RPL-PRG prevents sticking of valves and 0-rings at high temperatures or in freezing conditions. It provides an excellent seal between synthetic rubber and plastic parts in contact with metal in both high vacuum and pressure systems. It is used in a variety of food grade applications where high dielectric strength, water repellency and corrosive protection are necessary.

It is manufactured in conformance with NSF International guidelines and are fully compliant with Canadian Food Inspection Agency requirements for use where incidental contact is possible under Sections 21 CFR 178.3570 and 774.1 D78.

Typical applications include valve seats, 0-rings, flow meters, plug valves, electrical connectors, ignition components and as an assembly lubricant for rubber and plastic parts.

Method of Application:

No special handling precautions are required. Follow regular maintenance instructions as provided with original equipment. Although RPL-PRG is designed not to dissolve or react in the presence of many active processing materials and chemicals, care should be exercised. From a more comprehensive listing of specific materials and chemicals, please contact us. RPL-PRG has an approximate shelf life of 2 years from the date of manufacture when stored in the original container at an ambient temperature of roughly 24C (75F).
