How to Distinguish Normal Silicone with Silicone that can Pass European Food-grade Tests？

Silicone can be made in various shapes. We chose two kinds of silicone products to make a contrast between normal silicone with silicone that can pass European food-grade tests. Hope this can help you have a better understanding of different silicone.

On the left hand is a silicone that can pass European food-grade tests while the right hand is normal silicone. Now, we’ll show you normal silicone first.

When you pull normal silicone hard, the middle part of the silicone will turn white.

Now we’ll show you the silicone that can pass European food-grade tests. It will always be transparent whatever how you pull it.

This is the most intuitive way to distinguish silicone materials. Thank you!
