---|---|---|
Simple Lithium | 175 | 120 to 135 |
Lithium Complex | 250+ | 150 to 175 |

What is considered food grade lubricant?
Food-grade or food-safe lubricant is the name given to any industrial lubricant that is considered safe for incidental contact with items that may be consumed by humans or animals, as long as it does not exceed a certain concentration. Items that require food-grade lubricants for production include: Food. Beverages.
Can we use grease at high temperature?
Greases for very high temperatures (VHT) or Ultra High Temperatures (UHT) can be used in service at continuous temperatures ≥200°C and can withstand peaks of 300°C. These conditions require special chemistries, very different from traditional mineral greases.
Is White Lithium Grease food Safe?
There are misleading marketing claims that white lithium grease is food-grade. However, lithium-thickened grease is not accepted as food-grade H1 and does not comply with NSF category code H1. All lubricants, including food-grade lubricants, need to provide proper lubrication for metal-to-metal surface separation.
Is WD-40 heat resistant?
WD-40 High-Performance White Lithium Grease Lithium grease provides long-lasting protection against rust and corrosion due to water and heat resistant, withstanding temperatures of -18C to +145C.
What is the difference between the food grade lubricant classifications H1 H2 and H3?
Usually, when people refer to “food-grade” lubricants, they mean H1 lubricants. H2 lubricants can be used in food-processing facilities, but only where there is absolutely no possibility of contact with food. H3 lubricants are typically used to clean and prevent rust on hooks, trolleys and other such equipment.
Is Lithium Grease good for high temperature?
HEAT RESISTANCE: Lithium grease demonstrates excellent heat resistance. It is capable of withstanding very high temperatures and has a drip temperature of approximately 200° Celsius. This is another favourable characteristic when it comes to the auto industry.
Is White Lithium Grease good for high temperature?
Permatex White Lithium Grease is an all-purpose white lubricant for metal-to-metal and metal-to-plastic applications. This lubricant protects against rust, makes surfaces friction-free and withstands moisture and high heat.
