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.

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 24°C (75°F).
