Silicone is a full name for silicone rubber and silicone hose, which is a member of the rubber family.
Advantages
- Excellent resistance to high temperature (250-300℃) and low temperature (-40-60℃)
- Have good physiological stability
- Ability to withstand repeated harsh and disinfecting conditions
- Has excellent resilience and small permanent deformation (200 ℃ 48 hours not more than 50%)
- Breakdown voltage is (20-25KV/mm)
- Ozone resistant
- UV resistant
- radiation resistance, etc.
Judgment method
However, there are still many people who do not have a concept of silicone products and do not know what silicone is.
Silicone products have been widely used in our life, but due to the drive of profit, there is no shortage of fake silicone on the market, there are many black-hearted manufacturers in order to save costs to maximize profits, making a lot of counterfeit low-quality silicone hose, the second best.
These silicone hoses generally contain certain harmful substances, compared to the real non-toxic colorless and tasteless silicone products, will endanger our health, then these counterfeit low-quality silicone products how to identify it, the following we will discuss how to distinguish between real and fake silicone products:
1、From the aspect of characteristics
Silicone products are non-toxic, tasteless and colorless, with good texture and no harm to human body.
The general counterfeit silicone products are difficult to achieve these effects, counterfeit silicone products are generally toxic and pungent smell, and also rough.
2, from the feel side
The toughness and elasticity of silicone products are very good, not easy to be permanently deformed by external forces. And the feel will be smoother.
And counterfeit silicone products are easily deformed, and because the fake silicone products do not have a layer of grease-like substance on the surface. 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, the edge of the fire is black.
The real silicone products are carbon like combustion, flame uniform. White smoke, odorless.
No matter what color silica gel after burning the edge is white, burning residue for powder-like objects.
5、Test by chemical method
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 there is a blue color indicates that there is silicon element, proved to be silicone.
