Food grade silicone is generally made from imported raw materials, and the quality is determined right from the selection of these materials. Therefore, relevant quality inspection reports are essential when purchasing raw materials. This does not mean that regular silicone is of poor quality; rather, it indicates that the two types are used in different applications. Regular silicone products are made using standard silicone blending production, while higher-quality food grade products are made from food-grade fumed silica. We know that silica dioxide is one of the main components of silicone, and fumed silica has a higher purity and density compared to regular silica dioxide. As a result, the finished product will differ slightly, particularly in terms of tensile strength. Food grade silicone has a reinforcing effect on its tensile properties, preventing the appearance of whitening during stretching. Therefore, a simple way to identify whether a silicone product is food-grade is by examining this characteristic.

What is FDA?
FDA is the English abbreviation of U.S. Food and Drug Administration. It is an international medical review authority, authorized by the U.S. Congress, the federal government, and the highest law enforcement agency specializing in food and drug management. The FDA is a monitoring agency of government health regulation composed of professionals such as doctors, lawyers, microbiologists, pharmacologists, chemists, and statisticians dedicated to protecting, promoting, and enhancing the nation's health. Foods, drugs, cosmetics, and medical devices certified by the FDA are safe and effective for the human body. In nearly 100 countries including the United States, only FDA-approved materials, devices, and technologies can be used for commercial clinical applications

Conclusion
In an era of heightened food safety awareness, food grade silicone has gained widespread use in eco-friendly tableware, baking molds, baby products, and more, thanks to its non-toxic nature, high-temperature resistance (-40°C to 220°C), and chemical stability. Unlike regular silicone, food grade silicone uses fumed silica as raw material and is certified by international standards such as FDA and NSF to ensure safety in food contact. Consumers can identify food grade silicone by features like "stretching without whitening" and "no pungent odor." At GSUN, we offer professional silicone material development and provide food grade silicone solutions that meet international standards, helping you create safe and reliable products.
