What is the reason that brings about silicon rubber product to bounce inadequacy?

What is the cause of insufficient resilience of silicone rubber products? We all know that silicone rubber products are widely used in various fields mainly due to its good toughness and softness. Silicone rubber products are soft, tear-resistant, and do not deform, and are widely used in life. However, once silicone rubber products lose these unique excellent properties, they become meaningless. Some common silicone sealing products will also experience product deformation and insufficient toughness after long-term use, thus losing their original performance.

The lack of toughness of the product is mainly due to the various additives added in the raw materials, which will cause the product to have different properties. Among them, "white carbon black" is the main reason for the lack of toughness of the product, and white gray black is the main composition of the raw material of silicone rubber. One, the silica used in the production of materials with different hardness is also different, and the appropriate proportion of addition can also make the surface activity in the raw material.

In addition to raw material additives, the molding vulcanization of the product also has a certain impact, and the elasticity of the product is directly related to the hardness of the raw material. When molding vulcanization, adding too much vulcanizing agent will cause the fluidity to be too active, and the product produced is either too soft or too high in tension, and adding too little vulcanizing agent will cause the product to be vulcanized and unable to form. Secondly, the control of temperature and time during the molding process is also very important. Too short vulcanization time will cause the product to be too soft and long-term use will gradually lose its resilience. Too high molding temperature will cause the product to be too brittle, and the resilience will be too weak and easy to break.
