1. From the aspect of hand feel, silicone key products have good toughness and elasticity, are not easy to be permanently deformed due to external force, and the hand feel will be relatively smooth, while inferior silicone products are easy to be deformed and feel rough.






2. Use the lighter flame to burn silica gel. The inferior silica gel button will emit black smoke under the combustion of the flame, and the residue is black powder. No matter how you burn the high-quality silica gel button, it will only emit white smoke, and the combustion residue is white powder.






3. From the aspect of characteristics, silica gel key products are non-toxic, tasteless and colorless materials with good texture and no harm to human body. The raw materials of real silica gel are pure white and transparent, while ordinary fake and shoddy silica gel key products are difficult to achieve these effects. Inferior silica gel key products are generally toxic, pungent and rough.






4. Abrasion resistance of silicone keys






Wear resistance is generally reflected in the ability of whether the surface of silica gel products is easy to suffer loss. Good silica gel keys rarely rub off the product surface due to external factors, which does not affect the appearance, text and color of performance.






5. Elasticity of silicone keys






As we all know, silica gel is elastic. Good silica gel has high elasticity. High elasticity mainly comes from the movement of silica gel molecular chain segments.






6. Tear strength and tensile strength of silicone keys

Silica gel products with high tear strength have outstanding anti-destructive ability, long service life and are not easy to be disturbed by the external environment. Silica gel products with poor tear strength are generally prone to cracks in the tearing process, resulting in rapid expansion of cracks and damage.
