Identifying genuine and fake silicone bracelets

1. Fake silicone rubber wristbands are prone to deformation, while real silicone rubber will feel good rebound and have a relatively small long-lasting deformation when pulled.

2. If the surface of real silicone rubber is not specially treated, it will feel relatively lubricated when touched by hand, as there will be a layer of oily substance on the outer layer.

3. The surface of silicone rubber is prone to impurities such as dust and hair.

2、 Combustion comparison method:

1. The fake silicone rubber wristband has a black edge after being burned, while the real silicone burns with a white edge regardless of color, and the remaining residue is powder.

Burning method for genuine and fake silicone rubber wristbands

2. The fake silicone rubber wristband is burned in an open flame, with black smoke and a foul odor. And the real silicone rubber wristband is burned like carbon, with a uniform flame. White smoke, odorless.

The fake silicone rubber wristband is exposed to flames, smoky black, and has a foul odor. The real silicone rubber wristband burns like carbon, with a uniform flame. White smoke, odorless.

3、 Solution method:

Take silicone rubber and burn it and touch the smoke with a watch glass to collect white powder. Dissolve the powder in a hot solution of 40% sodium hydroxide (60 degrees Celsius). Take one drop of this solution and put it into a test tube. Add two drops of ammonium molybdate, gently heat it, cool it down, and add one drop of aniline solution and 3-8 drops of full sodium acetate solution. Observe the color response of the solution. If it appears blue, it indicates the presence of silicon, indicating that it is silicone rubber.
