Silicone is one of the common materials in life, it has a good anti-slip, fall resistance and other properties, in the industry has a wide range of applications, such as the electronics industry in the mobile phone cover, computer cover, etc., and a variety of kitchen utensils in life, such as: cups, bowls and chopsticks and so on.

In the process of use, it is found that some inferior silicone kitchen utensils will produce harmful gases when heated, which will cause certain harm to the human body. Therefore, for this material, we need to understand clearly, so as not to cause damage to the body. So, is silicone kitchen heating toxic?

1. In terms of composition,

Qualified silicone rubber is a kind of highly active adsorption material, the main component is silicon dioxide.

2. In terms of structure,

Silicone rubber is composed of organic two-terminal groups and inorganic hydrocarbon oxygen groups alternately connected to the chain of macromolecules, of which the organic end is a functional group, plays a functional role, and the other end of the inorganic group of chemical properties is more active, easy to be oxidized, so its surface often formed peroxides containing active hydrogen.

3, from the process point of view,

The traditional production method is to mix raw rubber with sulfur and vulcanize it at high temperature, then wash it, pickling it, and then dry it.

4. From the perspective of product quality,

High quality silicone rubber, the appearance is milky white, uniform color, no impurities, feel soft and elastic, with the finger press, there will be obvious rebound, and not easy to deformation.

5. Inferior products

The color is not pure, there are black spots, touch with the hand, there will be a feeling of sticky hands.

6, qualified products,

Will be printed on the packaging logo and the name of the manufacturer, and equipped with a certificate of conformity.

7, unqualified products,

Generally, there is no outer packaging, or only simple cartons, and some even have no cartons, placed directly on the ground, or piled randomly, without any signs.
