Is nylon pa6 considered food grade?

Whether Nylon PA6 is considered food-grade can be determined from the following aspects:

1️⃣ Specific Grades and Compliance

Food-grade PA6 exists: There are specific "food-grade" models or versions of Nylon PA6 material.
Must meet standards: Only PA6 that has been specially manufactured and certified to meet the strict regulations of agencies such as the US FDA (Food and Drug Administration) or EU 10/2011 regarding food contact materials can be considered food-grade.
Not all PA6 is suitable: Standard or industrial-grade PA6 usually does not have these food contact certifications and cannot be used in food applications.

2️⃣ Characteristics of Food-Grade PA6

High purity: Food-grade PA6 has extremely high requirements for material purity during the production process to ensure that no harmful substances are released when in contact with food.
Additive control: The use of additives or colorants that may be harmful to the human body is strictly controlled in these materials.
Low migration risk: It is designed so that the migration of tiny substances (such as low molecular weight components) that may leach from the material when in contact with food (even at specific temperatures) is extremely low, reaching safe limits.

3️⃣ Main Application Scenarios

Food processing equipment: Food-grade PA6 is commonly used in the manufacture of moving parts in food and beverage processing equipment, such as gears, bearings, rollers, and conveyor belt parts.
Wear resistance and strength: It utilizes the excellent mechanical properties of Nylon PA6 itself, such as high strength, wear resistance, and fatigue resistance, ensuring the reliability of the equipment during long-term operation.

4️⃣ Key Points for Selection and Use

Check certificates: When selecting Nylon PA6 for food-related applications, it is essential to obtain and confirm that the material supplier has a valid food contact compliance certificate, such as documents clearly stating compliance with FDA 21 CFR § 177.1500 or EU 10/2011.
Distinguish between models: It is crucial to distinguish between industrial-grade PA6 and food-grade PA6, as there are fundamental differences in their use.
