Silicone is a very common material with a wide range of applications in daily life, such as phone cases, silicone bracelets, silicone insoles, and so on. But do you know how many grades silicone has? How to distinguish them? This article will provide you with a detailed introduction to the grades and identification methods of silicone.

Silicone can be classified into industrial grade, food grade, and medical grade. Among them, industrial grade silicone is the simplest and most basic silicone, and is not suitable for direct contact with the human body or food. Food grade silicone is edible, meets food safety standards, and can directly come into contact with food, such as silicone used to make baking high-temperature coasters. Medical grade silicone is more advanced and mainly used in medical devices and supplies, such as breast implants, urinary catheters, etc.

1. Appearance

Firstly, pay attention to the appearance of silicone. Industrial grade silicone is usually darker in color, has a strong odor, and is more viscous and solidified. Food grade and medical grade silicone have clearer, cleaner, and odorless colors.

2. Price

The price of silicone grade also varies significantly. Industrial grade silicone has low cost, so the price is relatively cheap, while food grade and medical grade silicone have relatively high cost, so the price is even higher.

3. Manufacturer

In addition, the grade of silicone can also be preliminarily understood from the manufacturer of silicone. Legitimate silicone manufacturers provide complete accessories, certificates, reports, and other information such as production date and batch number for reference.

In short, the determination of silicone grade requires selecting corresponding products based on actual needs and usage scenarios, and choosing silicone produced by legitimate manufacturers. If you are unsure about how to choose, it is recommended to consult a professional or directly purchase silicone products with production licenses and relevant qualification certificates.

The above is an introduction to the grade of silicone and an explanation of the identification method. We hope it can help you use it correctly and choose the silicone products that are suitable for you.
