Castrol Optileb™GR 823 greases (previously called Molub-Alloy™ Foodproof 823 FM) were developed for general lubrication of food machinery. They have been approved as "physiologically safe" by the Landesgewerbe-Anstalt LGA Bayern. Optileb GR 823 greases have also been approved by the U.S. Department of Agriculture (NSF) as "H1" lubricants which can be used in the food and beverage industry even if incidental contact with food products is possible.

A select base oil blend plus an FDA approved thickener provide good adhesion, film strength and water-wash resistance even at elevated temperatures. Drip-free characteristics and the off-white color of Optileb GR 823 greases complement house keeping efforts in food and kindred industries.

A high performance combination of food grade additives provides excellent anti-wear protection. The combination of additives and blending techniques maximize rust and oxidation characteristics for effective rust protection and long service life of the grease.

Applications

Applications

 N/A Optileb GR 823 greases should not be mixed with greases using a different thickener. Lubrication intervals should be increased gradually to ensure complete removal of previous lubricant. At higher temperatures (above 100°C) relubrication intervals should be established by inspection.

Operating Temperature Range

 N/A -22 to 248 ºF

Features and Benefits

Features and Benefits

 N/A
  • H1 lubricants acceptable for use where incidental contact with food is possible.
  • Very high melting point and non-drip characteristics of this grease minimize product contamination.
  • Unique water resistance provides continuous protection even when equipment is washed down periodically.
  • Physiologically safe (approved by LGA Bayern) - base fluid and all other ingredients used in GR 823 comply with sections 178.3570 and 178.3620 of the FDA guidelines.
