With the continuous development and innovation of the silicone industry, due to the widespread application of silicone products in various industries, there are also more and more silicone products on the market. However, there are also some inferior or counterfeit silicone products. So, how should we judge the quality of silicone products when purchasing them?

I. Wear resistance
Wear resistance is the ability of silicone products to withstand wear and tear during production and molding. Good silicone products generally have a surface that is rarely rubbed off by external factors, and does not affect the appearance, text, or color of the product. And the surface characters of low-quality silicone products are prone to falling off.

II. Elastic
Silicone products have good elasticity because high elasticity mainly comes from the movement of silicone molecular segments. Therefore, when purchasing silicone products, first check the elasticity of the silicone product to determine its quality.

III. Tear strength and tensile strength
Silicone products with high tear strength have outstanding resistance to damage, long service life, and are not easily affected by external environmental interference. Silicone products with poor tear strength are generally prone to cracking during the tearing process, which rapidly expands and causes damage when subjected to force.

Ⅳ. Fatigue resistance
The phenomenon in which the structure and properties of silicone products change when subjected to alternating stress (or strain) is called fatigue. The phenomenon of damage to silicone products during the fatigue process is called fatigue failure.

Ⅴ. Five Hardness and tensile stress
The important indicators that reflect the rigidity (stiffness) of rubber materials are the forces required for silicone products to undergo certain deformations.

So when purchasing silicone products, the most important thing is to first look at wear resistance, elasticity, and tear strength. If it meets the requirements, it indicates that the silicone product is of good quality. If it does not meet the requirements, it should be abandoned to avoid financial losses.
