What are the characteristics of good quality silicone products?

With the continuous development and innovation of the silicone industry, due to the widespread application of silicone products in various industries, there are more and more silicone products on the market. However, there are also some inferior or counterfeit silicone products. So how do we buy silicone products To judge the quality of silicone products?
I. Abrasion resistance

  Abrasion resistance is due to the production and molding of silicone products. The surface of silicone products can withstand the loss. The surface of good silicone products is rarely rubbed 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 inferior quality silicone products are easy to drop.

Second, flexibility

  Silicone products have good elasticity, because high elasticity mainly comes from the movement of the molecular segment of the silicone, so when buying a silicone product, first look at the elasticity of the silicone product to judge the quality.

Three.Tear strength and tensile strength

  Silicone products with high tear strength have outstanding damage resistance, 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, which causes rapid expansion of the cracks when stressed, resulting in damage. phenomenon.

Fourth, fatigue resistance

   When a silicone product is subjected to alternating stress (or strain), the phenomenon that the structure and performance of the material changes is called fatigue. With the progress of the fatigue process, the phenomenon that causes the failure of silicone products is called fatigue failure.

V. Hardness and fixed elongation stress

  An important indicator of the rigidity (rigidity) of the rubber material. The two are the forces required for a certain deformation of the silicone product.
