With the continuous development and innovation of the silicone industry, silica gel products are widely used in various industries, and more and more silicone products are on the market. However, there are also some inferior or counterfeit silicone products on the market. When we purchase silicone products, we How to judge the quality of silicone products?
1. Abrasion resistance is the ability of silicone products to produce and shape, and the surface of silicone products can suffer from loss. Generally, the surfaces of good silicone products are rarely rubbed off the surface of the products due to external factors, which does not affect the appearance, text, and color of the performance. The quality of poor quality silicone products surface characters easily fall.
2. Silicone products have good elasticity, because the high elasticity mainly comes from the movement of the molecular segments of the silica gel. Therefore, when purchasing silica gel products, first look at the elasticity of the silicone products to judge the quality.
3. When the silicone product is subjected to alternating stress (or strain), the phenomenon of change in the structure and properties of the material is called fatigue. With the progress of the fatigue process, the phenomenon of destruction of silicone products is called fatigue failure. Therefore, fatigue resistance is also a method of distinguishing the quality of silicone products.
4. Silicone products with high tear strength have outstanding damage resistance, long service life, and are not easily disturbed by the external environment. Silicone products with poor tear strength are generally characterized by cracks in the tearing process, resulting in rapid expansion and cracking during stress. Destruction phenomenon.
5. Hardness and settling stress reflect the rigidity (rigidity) of the rubber material, both of which are the forces required for the silicone products to produce a certain deformation. It is also a method of distinguishing the quality of silicone products.
