What are the characteristics of good quality silica gel products?

With the continuous development and innovation of the silica gel industry, due to the wide application of silica gel products in various industries, more and more silica gel products are on the market. However, there are also some inferior or counterfeit silica gel products. How can we judge the quality of silica gel products when buying silica gel products?
1. Wear Resistance
Wear resistance is a property of the production and moulding of silica gel products. The surface of silica gel products can suffer wear and tear. The surface of good silica gel products is seldom rubbed off by external factors, without affecting the appearance, text and color of the products. And the surface characters of the inferior silica gel products are easy to drop.


2. Elasticity
Silica gel products have good elasticity, because the high elasticity mainly comes from the movement of silica gel molecular chains, so when buying silica gel products, first look at the elasticity of silica gel products to judge the quality.


3.Tear strength and tensile strength
Silica gel products with high tear strength have outstanding anti-destructive ability, long life, and are not easily disturbed by external environment. Silica gel products with poor tear strength are generally prone to cracks in the tear process, which lead to the phenomenon of rapid expansion of cracks and damage when subjected to stress.


4. Fatigue Resistance
When silica gel products are subjected to alternating stress (or strain), the phenomenon that the structure and properties of materials change is called fatigue. With the fatigue process proceeding, the phenomenon that leads to the destruction of silica gel products is called fatigue failure.


5. Hardness and Tensile Stress
Important indicators of rigidity (stiffness) of rubber materials are the forces required to produce certain deformation of silica gel products.
