1. From the perspective of hand feel, silicone key products have good toughness and elasticity, are not easy to be permanently deformed by external forces, and feel relatively smooth, while inferior silicone products are easy to deform and feel rough to the touch.
2. Use a lighter to burn the silica gel. Inferior silica gel buttons will emit black smoke when the flame is burning, and the remainder is black powder. No matter how you burn it, the high-quality silica gel buttons will only emit white smoke. Burn the remainder. It is white powder.
3. In terms of characteristics, the silicone key products are non-toxic, odorless and colorless, with good texture and no harm to the human body. The real silicone material is pure white and transparent, while the general fake and inferior silicone key products are difficult to achieve these effects, and they are inferior. Silicone keypad products are generally toxic, pungent, and rough.
4. The abrasion resistance of silicone buttons is generally expressed in the ability of the surface of silicone products to suffer loss. Good silicone buttons generally rarely rub off the surface of the product due to external factors, and do not affect the appearance, text, and colour.
5. The elasticity of silica gel buttons. As we all know, silica gel is flexible. Good silica gel buttons have high elasticity. The high elasticity mainly comes from the movement of silica gel molecular segments.
6. The tear strength and tensile strength of the silicone buttons. Silicone products with high tear strength have outstanding resistance to damage, have a long life, and are not easily interfered by the external environment. Silicone products with poor tear strength are generally prone to cracks during the tearing process. , So that the phenomenon of rapid expansion and cracking when subjected to force, resulting in damage.
