How to identify the silicone phone holder?

There are a lot of silicone phone holders on the market now, with varying prices and quality, and I'll teach you how to easily identify the good and the bad.

First of all, look at the appearance, touch the feel, some with poor silicone material, made out of the card holder bracket feel very poor, the surface of many small particles, and the hairy edge is very big, such a bracket bracket is not good.

Secondly, check the thickness, there are many factories in order to reduce costs, the product is made very thin very thin, the normal thickness should be 4-5mm, 18g or so.

Look at the 3M stickers, general tear off the silicone card holder back of the 3M 300LSE stickers, the release paper is automatically separated from the adhesive paper, adhesive paper to stay in the bracket ferrule above, and can be used repeatedly, and tear off the phone does not leave traces.

In order to reduce the cost, many factories use rusty and inflexible shrapnel to make the bracket ferrule, which seriously affects the use performance, you can use scissors or knife to scrape off the silicone on the surface of the shrapnel.

If the flame is white, the ashes are also white, it means the silicone is free of impurities; if the flame is black, or the ashes are black, it means the silicone is not pure.
