How to distinguish the quality of silicone products?
Silicone products have been in our lives for many years, and now they are a very common item in our lives. We all know that silicone products can be used in many fields, such as aviation, industry, medical care, life, gifts, etc. There will be silicone items. Abrasion resistance is possessed by the production and molding of silicone products. The surface of silicone products can suffer loss. Generally, the surface of 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 structure and performance of the material change 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 resistance to damage, have a long life, and are not easy to be interfered by the external environment. Silicone products with poor tear strength are generally prone to cracks during the tearing process, thereby being stressed. The phenomenon of rapid expansion of cracking and destruction.
Hardness and constant elongation stress: Hardness and constant elongation stress reflect important indicators of the rigidity (rigidity) of silicone materials, and both are the forces required for a certain deformation of silicone products. It is also a way to distinguish the quality of silicone products.
The quality of silicone products can also be distinguished from the smell. High-quality silicone products have no taste; the other is the feel. High-quality silicone products look smooth on the surface, while inferior products have a rough feel.
