Silicone rubber, whose full name is silicone rubber and silicone rubber, is a member of the rubber family. Because it has excellent resistance to high temperature (230 ℃) and low temperature (-40 ℃) performance, has good stability, can withstand repeated harsh and disinfection conditions, has excellent resilience and permanent deformation (200 ℃ 48 hours not more than 50%), breakdown voltage (20-25KV/mm), ozone resistance, UV resistance, radiation resistance and other characteristics. Therefore, it has been widely used in our life. But now there are still many people do not have a concept of silicone products, do not know what silicone is, some people think that refers to the common silicone baby pacifier, some people completely silicone and latex as the same thing, do not know how to choose these silicone products.

Silicone products have been widely used in our life, but due to the drive of profit, there is no shortage of fake silicone in the market, there are many black-hearted manufacturers in order to save costs to maximize profits, making a lot of counterfeit low-quality silicone products, the second best. These silicone products generally contain certain harmful substances, compared to the real non-toxic colorless and tasteless silicone products, will endanger our health, so how to identify these counterfeit low-quality silicone products, the following we will discuss how to distinguish between real and fake silicone products:.

1, from the characteristics, silicone products are non-toxic, tasteless and colorless, good texture, no harm to the human body, while the general counterfeit silicone products are difficult to achieve these results, counterfeit silicone products are generally toxic and pungent smell, and also relatively rough.

2, in terms of feel, silicone products have good toughness and flexibility, not easy to permanently deformed by external forces, and the feel will be smooth, and counterfeit silicone products are easy to deformation, and because the surface of the fake silicone products without a layer of grease-like substances. So it will be rougher to touch.

3、Because of the natural adsorption characteristics of silica gel, so the silicone surface is easy to stick dust, hair and other fine impurities.

4, through the burning comparison can be concluded: fake silicone rubber products are open fire burning, smoke black, and there is a bad smell, by the fire after the edge is black, and the real silicone products are carbon like burning, flame uniform. White smoke, odorless. No matter what color silica gel after burning the edge is white, burning residue for powder-like objects.

5, tested by chemical methods: take silicone rubber burning and surface dish contact smoke, collect white powder, the powder dissolved in 40% strong alkali hot solution (60 degrees) take a drop of the solution into the test tube, add two drops of ammonia molybdate, slightly heated, cooled by adding a drop of aniline solution and 3-8 drops of saturated sodium acetate solution, observe the color reaction of the solution, if the appearance of blue indicates the presence of silicon elements, proved to be silicone rubber.
