Can food grade silicone hose conduct electricity? The answer is “no”. Because the raw material is a good insulating material. However, it can conduct electricity after special treatment.
So, how does silicone tube conduct electricity?
Conductive food-grade silicone tube is made of food-grade silicone tube as the base material, adding conductive fillers, cross-linking agents, etc. However, the principle of conduction is that when the content of conductive fillers increases to a certain critical value, a complete conductive path network is formed inside the silicone. Then the resistance of the rubber will drop sharply. There is a very narrow mutation area in the relationship between resistance and the amount of conductive fillers. Any slight change in the amount of conductive fillers will cause a significant change in the resistance of the rubber, which is called percolation. The critical amount of conductive fillers is usually called the percolation value.
However, the conductive food-grade silicone tube evenly distributes conductive particles such as silver-plated copper powder in the tube. They are interconnected through the contact of conductive particles to achieve good conductive properties. Its main functions are sealing and electromagnetic shielding. The shielding performance is as high as 120 dB (10 GHz). Conductive food-grade silicone tube has good electromagnetic sealing and water vapor sealing capabilities. In addition, it has good conductivity under a certain pressure.
