Question: What is food grade lubricating grease? What are the requirements? answer:

Food grade lubricating grease refers to lubricating grease that meets food hygiene requirements and can be applied to food processing and packaging equipment. The purpose of food grade lubricating grease is to ensure the safety and hygiene of food, in order to prevent improper spillage, mixing, or dripping into the appropriate food or food packaging. Food grade lubricating grease needs to meet the following requirements:

1. Legal registration: Liquid and paste food grade lubricants must be registered with the drug regulatory department and obtain necessary permits. These licenses demonstrate that the components and uses of the product comply with health and safety requirements.

2. Do not contain harmful substances: The product must not contain substances that are harmful to human health, heavy metals such as lead, mercury, chromium, and their compounds, as well as substances such as nitrite and iron oxide when wet.

3. Excellent extreme pressure performance: Lubricating grease must have good extreme pressure performance to ensure reliable lubrication under high speed, high temperature, high pressure, and heavy load conditions.

4. Excellent wear resistance and stability: With good extreme pressure performance and oxidation stability, it is not easy to spill or spoil, easy to clean, and will not pollute or corrode food or packaging materials.

5. Corrosion resistance: It has excellent water washing resistance and corrosion resistance, and can adapt to the requirements of various occasions such as metallurgy, garbage treatment, food processing, light industry and textile, etc., at different temperatures, humidity, and environments.

6. Long life: With a long and durable lifespan, it can be used for a period of time without reducing its lubrication effect or polluting food.

7. Environmental performance: It does not contain harmful substances such as CFC and HCFC, and will not pollute the environment and produce negative effects.

In short, food grade lubricating grease not only needs to have excellent lubrication performance and stability, but also needs to comply with food hygiene standards to ensure a safe, reliable, and clean usage environment.
