First of all, to see whether the quality of silicone products is an important factor is the elasticity, it is well-known that silicone is elastic, good silicone products, high elasticity, high elasticity is mainly from the movement of the molecular chain of silicone, for the user to say that flexibility is the first inspection of.
Second, to see the tear strength and tensile strength of silicone products, silicone products with high tear strength have outstanding resistance to damage, long life, and are not easily affected by external environment. Silicone products with poor tear strength are generally easy to tear. There is a crack, which quickly expands and cracks and causes damage.
In addition, to see the wear resistance of silicone products, wear resistance is generally expressed in the surface of the silicone products are vulnerable to the loss of the ability, good silicone products, the general surface is rarely rubbed off the surface due to external factors, does not affect the performance of the appearance, text ,colour.
Then, depending on the hardness and the tensile stress of the silicone products, they all represent the important indicators of the stiffness (stiffness) of the rubber material. Both are the forces required for the silicone products to produce a certain deformation.
Finally, look at the fatigue and fatigue failure of silicone products and fatigue failure. When silicone products are subjected to alternating stress (or strain), the phenomenon of changes in the structure and properties of materials is called fatigue. With the progress of the fatigue process, the phenomenon of destruction of silicone products is called fatigue failure.
