With the continuous development and innovation of the silicone industry, silicone products are widely used in various industries, and there are more and more silicone products on the market. However, there are also some inferior or counterfeit silicone products on the market. So when buying silicone products, we How to judge the quality of silicone products?
Abrasion resistance
Abrasion resistance is the ability of the production and molding of silicone products. custom silicone mold manufacturer The surface of silicone products can suffer loss. Generally, the surface of good silicone products rarely rubs off the surface of the product due to external factors, and does not affect the appearance, text, and color of the performance. The characters on the surface of low-quality silicone products are easy to fall off.
elasticity
Silicone products have good elasticity, because the high elasticity mainly comes from the movement of the silicone molecular chain, so when buying silicone products, first look at the elasticity of the silicone products to judge the quality.
Fatigue resistance
When silicone products are subjected to alternating stress (or strain), the phenomenon of changes in the structure and properties of the material is called fatigue. As the fatigue process progresses, the phenomenon that causes the destruction of silicone products is called fatigue failure. Therefore, fatigue resistance is also a way to distinguish the quality of silicone products
Tear strength and tensile strength
Silicone products with high tear strength have outstanding anti-destructive ability, a long life, and are not easily interfered by the external environment. Silicone products with poor tear strength are generally prone to cracks during the tearing process, which will rapidly expand cracks when subjected to force and cause damage. Phenomenon.
Hardness and tensile stress
Hardness and constant elongation stress reflect important indicators of the rigidity (rigidity) of rubber materials, and both are the force required for a certain deformation of silicone products. It is also a way to distinguish the quality of silicone products
