Silicone spacers are mainly made of high-grade silicone from silicon factory, they are soft to the touch, strong in elongation and very durable. The material of the silicone gasket is silica gel, which has excellent high and low temperature resistance, can maintain good flexibility at high temperatures, and has the advantages of ozone resistance and weather aging resistance, and is suitable for thermomechanical sealing gaskets. Since it is non-toxic, it is used in the manufacture of heat insulation materials, insulation products and medical rubber products. At the same time, it has many excellent properties such as waterproof, flame retardant, high temperature resistance, electrical conductivity, wear resistance, oil resistance, etc., and is widely used in machinery, electronics, plumbing and other industries.

Silicone gaskets are common items in our daily life! How to determine the quality of silicone gaskets when purchasing silicone gaskets? It can be analyzed from the following five aspects.

1. Abrasion resistance: Abrasion resistance is the ability of the surface of silicone products to suffer from wear and tear in the production and molding of silicone gaskets. The surface of the silicone gasket is rarely wiped off the surface of the product due to external friction factors, which will not affect the appearance and color of the product. Characters on the surface of inferior silicone products are easy to fall off.

2. Elasticity: Silicone gaskets have good elasticity, because high elasticity mainly comes from the movement of silicone molecular chains, so when purchasing silicone products, first look at the elasticity of silicone products to judge their quality.

3. Fatigue resistance: When silicone products are subjected to alternating stress (or strain), the phenomenon that the structure and performance of the material change is called fatigue. As the fatigue process progresses, the phenomenon that leads to the destruction of silicon products is called fatigue failure. Therefore, fatigue resistance is also a way to distinguish the quality of silicone products.

4. Tear strength and tensile strength: Silicone gaskets with high tear strength have excellent damage resistance, long life, and are not easily affected by the external environment. Silicone products with poor tear strength are usually prone to cracking during the tearing process, so when stressed, they will expand rapidly and crack, causing damage.

5. Hardness and constant elongation stress: Hardness and constant elongation stress reflect the important indicators of the stiffness (rigidity) of rubber materials, and both are the forces required for a certain deformation of silicon products. This is also a way to distinguish the quality of silicon products.
