1. Strong acid and alkali: Wear-resistant and High Pressure Silicone Hose will be corroded when it encounters high concentration of hydrochloric acid and high concentration of nitric acid (high concentration will be affected, and it can work normally if the concentration is not high). Silicone is an elastic material rather than a solid material, and conventional materials of this kind cannot withstand strong acid. The strong alkali refers to chemicals such as hydroxide and potassium calcium hydroxide. If the silicone hose is in contact for a long time, the chemical formula of the silica gel will be unstable and will be decomposed. However, the pH value of the wound silicone hose can operate normally if it is below 6. How to solve these problems? A fluorosilicone material can be added between the materials when the silicone hose is extruded. The molecular structure of the winding silicone hose can be changed to achieve a certain function, and this situation can be completely avoided after the product is added with fluorosilicone, so you will no longer be afraid Strong acid and strong base.

 

2. Oily substances: Wear-resistant and high-pressure silicone hoses can’t come into contact with most concentrated oils or compounds, but fortunately, the silicone hose used on the optical fiber basically does not need to come into contact with high-concentration oily substances, because oily substances will melt them. For example, if you contact gasoline silicone for a long time, it will be slowly decomposed and volatilized, but you can add inert materials such as fluorine to the product to perfectly solve these problems. For example, automobile silicone hoses can be used flexibly in gasoline engine oil because they are added this material.
