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.

So how do we distinguish the quality of the silicone pad and the quality of the product when we purchase or customize the delivery?

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 rubber gaskets 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 rubber gaskets 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 change in the structure and performance 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

The quality of silicone pads can also be distinguished from the smell. The high-quality silicone products have no taste, and the feel is on the surface. The surface of the high-quality silicone pads looks smooth, and the inferior products have a rough feel!
