How to distinguish the advantages and disadvantages of silicone pads
Silicone products have been in our lives for many years and are now a very common item in our lives. We all know that silicone products can be used in many fields, such as aviation, industry, medical, life, gifts, etc. I will have silicone items.
So how do we identify the quality of the silicone mat and the good and bad products when we purchase or customize the delivery?
Wear resistance is the production of silicone products. The surface of silicone products can withstand the loss. Silicone rubber gaskets generally have little surface friction due to external factors, and do not affect the appearance, text and color of the performance. The surface characters of poor quality silicone products are easy to fall off.
Silicone rubber gaskets have good elasticity, because the high elasticity mainly comes from the movement of the molecular segment of the silica gel, so when purchasing silicone products, first look at the elasticity of the silicone products to judge the quality.
When a silicone product is subjected to alternating stress (or strain), the phenomenon that the structure and properties of the material change is called fatigue. As the fatigue process progresses, the phenomenon that the silicone product is destroyed is called fatigue damage. Therefore, fatigue resistance is also a method to distinguish the quality of silicone products.
Tear strength and tensile strength
The silicone product with high tear strength has outstanding anti-destructive ability and long life, and is not easily interfered by the external environment. The silicone product with poor tear strength is generally prone to crack during the tearing process, and thus rapidly expands cracking and causes damage. phenomenon.
Hardness and tensile stress
Hardness and modulus of stress represent an important indicator of the rigidity (stiffness) of a rubber material, both of which are the forces required for a certain deformation of a silicone product. Is also a way to identify the quality of silicone products
It is also possible to distinguish the quality of the silicone pad from the smell. The high-quality silicone product has no taste, and the top is the top. The high-quality silicone pad is smooth on the surface, and the inferior product feels rough on the hand!
