Silicone rubber has many excellent functions. In terms of price, it is still lower than fluorine rubber. Its application range is very common, from medical food industry, electronics industry, automobile industry, construction industry to aviation industry, covering almost all industry applications. How to distinguish the quality of silicone rubber is very important.
How to distinguish genuine and fake silicone products?
For real silicone products, such as silicone buttons, the surface layer will feel smoother to the touch, because there will be a layer of grease-like substance on the surface layer.
Inferior silica gel buttons are prone to deformation, while real silica gel rebounds very well, and the deformation is relatively small.
Use a blade to cut a small piece of silica gel and burn it with fire. If only white smoke and sparks are emitted, it will not burn and the burned white powder will be silica gel. If there is an odor, there may be some problems with the vulcanizing agent used.
The surface of silicone rubber is easy to stick to dust, such as relatively light impurities such as hair.
Good silica gel has no peculiar smell and will not soften and change color when exposed to heat.
When the fake silicone rubber is burned with a fire, it burns with an open flame, emits black smoke, and has a foul smell.
