It does not react with acidic or alkaline substances in food, ensuring food safety.

According to the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), food-grade silicone is safe and widely used in food contact materials.

Is Medical-grade Silicone Toxic? The Safety Standards Are Stricter

Medical-grade silicone needs to meet higher safety standards to ensure it is harmless when used in the human body. This type of silicone is commonly used in manufacturing medical devices, such as pacemakers, artificial joints, and medical catheters. Medical-grade silicone undergoes rigorous biocompatibility testing to ensure it does not cause adverse reactions or release harmful substances in the human body. These tests include:

Cytotoxicity Testing

To check if the material is toxic to cells.

Sensitization Testing

To ensure the material does not cause allergic reactions.
