How to distinguish the quality of silicone key case?

First, smell it, then try the feel, and finally see how it fits.

1. Check the surface when it is dirty or damaged;

2. Check whether the parting line is obvious;

3. Whether the fuel injection is even and the thickness is moderate;

4. If there is a silk screen group, observe whether the silk screen group is accurate and continuous.

Abrasion resistance: The abrasion resistance is possessed by the molding of the silicone key case. The surface of the silicone key bag can suffer loss. The surface of a good silicone key cover rarely rubs off the surface of the product due to external factors and does not affect it. The appearance, text, and color of the performance. The characters on the surface of the low-quality silicone key case are easy to fall off.

Elasticity: The silicone bag has good elasticity, because the high elasticity mainly comes from the movement of the silicone molecular chain, so when buying a silicone key holders, first look at the elasticity of the silicone key case to judge the quality.

Fatigue resistance: When the silicone key case is subjected to alternating stress (or strain), the change in the structure and performance of the material is called fatigue. As the fatigue process progresses, the phenomenon that causes the destruction of the silicone key case is called fatigue failure. Therefore, fatigue resistance is also a way to distinguish the quality of silicone key cases.

Tear strength and tensile strength: Silicone key cases with high tear strength have outstanding resistance to damage, have a long life, and are not easily disturbed by the external environment. Silicone key cases with poor tear strength are generally prone to cracks during the tearing process. The phenomenon of rapid expansion and cracking when subjected to force, resulting in damage.

Hardness and constant elongation stress: Hardness and constant elongation stress reflect important indicators of the rigidity (stiffness) of rubber materials, both of which are the force required for a certain deformation of the silicone key case. It is also a way to distinguish the quality of the silicone key case.
